### Classifying spaces for families of subgroups

2010-12-04 through 2010-12-05
Columbus, OH; USA

Meeting Type: conference

Subject Area: algebraic topology, geometric group theory, assembly conjectures

Contact: Jim Fowler

### Description

Classifying spaces play a prominent role in topology. In recent years, there has been increasing interest in classifying spaces for group actions with isotropy in prescribed families of subgroups (e.g. finite subgroups, virtually cyclic subgroups, finite by cyclic subgroups, hyperelementary subgroups, etc). One reason for this is that these classifying spaces feature prominently in various "assembly map'' conjectures, such as the Baum-Connes conjecture and the Farrell-Jones isomorphism conjectures. This conference proposes to bring together mathematicians working on such classifying spaces, both from the constructive side (i.e. how to build "small'' models) as well as the applications side (i.e. what good are these models).

http://milnor.math.ucl.ac.be/plwiki/TopologieAlgebriqueUCL/HowToArriveAtTheMathBuilding

Here are summaries of the talks

9h45-10h45 Greg Lupton (EPFL/Cleveland State University)
"On topological complexity" Joint work with J. Scheerer.

11h00-12h00 Gael Collinet (Univ. Strasbourg)
"Homology stability for automorphism groups of free products." (with A. Djament and J. Griffin)

We will give a proof of the following result which was conjectured by A. Hatcher and N. Wahl : let $G$ be a group that is irreductible for the free product and non-isomorphic to $\mathbf Z$. The natural maps $Aut(G^{*n})\to Aut(G^{*n+1})$ induce isomorphisms in integral homology of degree $i$ for $n\geq 2i+2$.

14h15-15h15 Nathalie Wahl (Univ. Copenhague) "Hochschild homology of structured algebras and TCFTs"

Abstract: Generalizing the work of Costello, we consider the Hochschild complex as an operator on certain types of functors (which we think of as generalized "open" field theories) and describe the structure induced by the original functor on its Hochschild complex ("closed" field theories). Applying this to the case of strict Frobenius algebras, we obtain an action of a complex of Sullivan diagrams on the Hochschild complex of such algebras, with implications in string topology using the work of Lambrechts-Stanley. This is joint work with Craig Westerland.

15h30-16h30 Nguyen Dang Ho Hai (UCL)
Résolution injective instable de la cohomologie modulo $p$ d'un spectre de Thom.

Résumé: Soit $p$ un premier et soit $\rho_n$ le fibré vectoriel associé à la représentation régulière réelle réduite du $p$-groupe abélien élémentaire $(Z/p)^n$, On note $L(n,m)$ le facteur stable de l'espace de Thom du fibré $m\rho_n$, associé à la représentation de Steinberg de $F_p[GL_n(F_p)]$. Les spectres $L(n,m)$ avec $m$ impair apparaissent dans la description des étages non contractiles de la tour de Goodwillie du foncteur identité évaluée en la sphère $S^m$. Dans cet exposé, on construit de manière explicite une résolution injective minimale de $H^*(L(n,3);F_p)$ dans la catégorie des modules instables sur l'algèbre de Steenrod modulo $p$. A l'aide de la théorie de Lannes et Zarati sur les foncteurs dérivés du foncteur de déstabilisation, cette résolution injective est utilisée pour obtenir un résultat de type "conjecture de Segal" pour la cohomotopie du spectre $L(n,3)$.

Meeting Type: workshop

Subject Area: algebraic topology, algebraic geometry, hodge theory

Contact: see conference website

### Description

This posting announces the 2011 Talbot Workshop, Non-Abelian Hodge Theory, mentored by Carlos Simpson.

The workshop will constitute a week-long retreat with talks and organized discussions during the mornings and evenings; the afternoon schedule will be kept clear for informal discussions and collaborations. The workshop will generally focus on understanding the representations of fundamental groups of algebraic varieties, modulated according to the participants' interests. Topics developed may include the harmonic theory relating the moduli of Higgs bundles to the moduli of G-bundles with flat connection, deformation theory, the topology of character varieties and symplectic/hyperkahler structures on moduli spaces, and--as time allows--further directions of research, such as connections to Geometric Langlands, extending Hodge theory to account for higher homotopy types, and studying non-compact cases.

The workshop discussions will have an expository character and will be aimed at graduate students and junior faculty interested in this area. Most talks will be given by participants of the workshop.

Further information about the workshop will become available on the workshop website. Interested participants should fill out the application form there by January 31, 2011. Due to funding and space constraints, we may be unable to host all applicants--the organizers will notify applicants by February 10, 2011, if we are unable to accommodate them. We will then solicit volunteers among the participants to give the workshop's talks.

Please note that the website also contains information about--and notes collected from--past Talbot workshops: Twisted K-Theory and Loop Groups (mentored by Constantin Teleman), Fukaya categories (mentored by Paul Seidel), Affine Lie Algebras and Chiral Structures (mentored by Dennis Gaitsgory), Topological modular forms (mentored by Michael Hopkins), Automorphisms of manifolds (mentored by Michael Weiss), Geometric Langlands (mentored by David Ben-Zvi), and Geometric models of elliptic cohomology (mentored by Stephan Stolz).

If you are interested in participating or would like to receive further information about the workshop, please visit the website, or e-mail talbotworkshop (at) gmail.com. We may be able to subsidize participants' travel expenses. Please note that the number of participants will be strictly limited for space reasons.

The lectures will start from a basic knowledge of simplicial sets and proceed to current frontiers. Speakers: • Prof Ieke Moerdijk (Nijmegen/Sheffield) • Dr David Gepner (Regensburg) • Dr Michael Shulman (UC San Diego) Background: In the past decade homotopy theory and higher category theory have increasingly become essential tools in an ever expanding list of fields of mathematics. These tools have also shown their importance in parts of computer science and logic. The first strand of the mini-school will be the Lurie-Joyal theory of infinity categories. It is a profoundly important foundation for homotopy theory, higher category theory, and derived algebraic geometry. Infinity categories are central to Lurie's proof of the Baez-Dolan cobordism hypothesis, they are becoming increasingly important in representation theory such as through recent developments in the Geometric Langlands Programme, and they also play a role in the Fukaya Categories of Kontsevich's Homological Mirror Symmetry Conjectures. This area has been progressing extremely rapidly in the recent years and there is a need for many young researchers to learn it. The second strand will be Voevodsky's type-theoretic univalent foundations. Type theory sits at an intersection of mathematics, logic and computer science. Voevodsky, after winning a Fields Medal for his work bringing homotopy theory to algebraic geometry, has since 2005 focused on constructing a profound new foundation for mathematics through an interplay between homotopy theory and type theory. This is an exciting new subject that deserves attention.

We hope that you will pass this information along to your graduate students and encourage them to attend. We think it is a wonderful opportunity! There is limited funding available, and priority will be given to those students in your department who are able to find additional funding. But we strongly encourage everyone to apply! About the Symposium: The University of Iowa mathematics department has received recognition for its outstanding minority mentoring program and has made a commitment to increase the number of minority graduate students and scientists. The Underrepresented Students in Topology and Algebra Research Symposium (USTARS) is a conference for graduate students proposed by a group of underrepresented students in the University of Iowa mathematics department and is largely run and organized by graduate students. The conference is structured so that speakers give 30-minute parallel research talks with one distinguished graduate student giving a 1-hour presentation on Saturday and a mentoring lunch on Sunday. We have also invited Prof. Federico Ardila, Associate Professor, San Francisco State University and Profesor Adjunto, Universidad de Los Andes, Colombia to be our plenary speaker. There is also a poster session for graduate students not chosen to give a talk to present. The broader impact of this event is that graduate students who attend USTARS are better equipped to find academic positions and continue the cycle of research and collaboration. More information on the conference and the application to attend, DUE February 4, 2012, can be found on the website. ### Workshop on applications of algebraic geometry to statistics, signal processing, complexity and other areas 2012-04-25 through 2012-04-27 Texas A&M University College Station, TX; USA Meeting Type: workshop Subject Area: algebraic geometry Contact: see conference website ### Description Workshop on applications of algebraic geometry to statistics, signal processing, complexity and other areas.

Notre Dame Notre Dame, IN; USA Meeting Type: Undergraduate summer school Subject Area: low dimensional topology Contact: see conference website ### Description This week-long summer school will consist of lectures and group problem solving activities aimed at introducing undergraduates to basic ideas from low-dimensional topology. Topology is the mathematical study of shapes, and low-dimensional topology is the study of shapes that we can (or almost can) "see". Central objects of study are knots (like those tied by scouts) and surfaces (like the "edge" of a donut). In addition to introducing students to basic objects in low-dimensional topology, the program will seek to inspire participants with a glimpse of recent developments at the frontier of research in this area. Participants should have completed courses in linear algebra and multivariable calculus, and will ideally have had exposure to some abstract algebra, although we will consider all applications. The main lecturers will be: Margaret Doig (Indiana University) Joshua Greene (Boston College) Matthew Hedden (Michigan State University) ### Oberwolfach Seminar on Surgery Theory 2012-05-27 through 2012-06-02 MFO Oberwolfach; Germany Meeting Type: seminar Subject Area: algebraic topology Contact: see conference website ### Description The seminar is intended for PhD students and recent postdocs.

Tying a knot in a field is a different story, because the whole of space must be filled in a way that matches the knot being tied at the core. The possibility of such localized “knottedness” in a space-filling field has fascinated physicists and mathematicians ever since Kelvin’s “vortex atom” hypothesis, in which the atoms of the periodic table were hypothesized to correspond to closed vortex loops of different knot types in a perfect Eulerian fluid. In recent years, the idea of knotted fields has gained a renewed interest, as the role of topology has been appreciated in a range of physical systems, including nonlinear field theories, liquid crystals, quantum wavefunctions, condensates, and optical fields. Crucially, experimental techniques are at a stage now where knotted and linked topological defect filaments have been engineered in laser light and in liquid crystals. In these cases, the field is some function of 3D space (complex scalar optical amplitude, or a liquid crystal nematic director, in which the defects are nodal and disclination lines, respectively). Meanwhile, there has been continued interest in topological fluid dynamics, as well as developments in relevant branches of abstract knot theory, including knotted solutions of PDEs and fibered knot theory. At the same time, topological braiding has become a cornerstone of quantum computing and addresses similar questions of manipulation and measurement of entangled fields. Collectively, these manifestations create a rich and substantive landscape for the exploration of unifying ideas. This program will bring together experts in these diverse fields; in particular, physicists working on knotted fields in the laboratory, mathematicians interested in applying tools of topology, and theorists interested in proposing new phases of matter and light. ### Homotopical algebra and its applications 2012-06-25 through 2012-06-29 Luminy; France Meeting Type: conference Subject Area: algebraic topology, homotopical algebra Contact: see conference website ### Description An international conference to celebrate the 60th birthday of Yves Felix.

Topic: The 2013 workshop, aimed toward graduate students and other young researchers, will focus on understanding chromatic homotopy theory. Developed by many mathematicians throughout the past few decades, this theory has produced powerful structural and calculational principles in topology and remains a highly active research area. Topics covered or touched on will include the chromatic spectral sequence; the landmark nilpotence and periodicity theorems of Devinatz, Hopkins and Smith; Morava's K- and E-theories; topological modular and automorphic forms; Gross-Hopkins duality; the telescope and chromatic splitting conjectures; and possibly others as time allows. Mentor: The 2013 Talbot Workshop will be mentored by Mark Behrens of MIT and by Tyler Lawson of University of Minnesota, Twin Cities. Format: The workshop discussions had an expository character and the talks were given by the participants of the workshop. The afternoon schedule was kept clear for informal discussions and collaborations. Timeline: Interested participants should fill out the application form by noon on Monday, December 3, 2012. Due to funding and space constraints, we may be unable to host all applicants--the organizers will notify applicants by Tuesday, December 11, 2012, if we are unable to accommodate them. We will then solicit volunteers among the participants to give the workshop's talks. Funding: We will cover all local expenses including lodging and food. We also have limited funding available for participants' travel costs. Who should apply: Talbot is meant to encourage collaboration among young researchers, particularly graduate students. To this end, the workshop aims to gather participants with a diverse array of knowledge and interests, so applicants need not be an expert in the field. In particular, students at all levels of graduate education are encouraged to apply. Background reading: This year we will ask participants to be familiar with some topics prior to arrival--these include (1) the basics of spectra, (2) the relationships between complex cobordism, formal group laws, and Brown-Peterson cohomology, (3) Bousfield localizations, and (4) the Adams and Adams-Novikov spectral sequences. Basic resources and references will be provided for learning this material, and we will provide further details as the workshop approaches. Information: Further information about the workshop (and the application) are available at: http://math.mit.edu/talbot The website also contains information about--and notes collected from--past Talbot workshops. If you have any questions, please do not hesitate to e-mail the organizers at talbotworkshop (at) gmail.com.

He will give a series of three one-hour lectures on "Riemannian Hyperbolization". CONTRIBUTED TALKS: Participants are invited to contribute talks. FUNDING: The workshop is partially supported by the National Science Foundation and Calvin College. Limited funds will be available to support travel and local expenses of participants. Priority will be given to graduate students and those without other funding sources. ABSTRACT OF THE LECTURES: Negatively curved Riemannian manifolds are fundamental objects in many areas of mathematics, but very few examples are known: besides the hyperbolic ones, the other known examples are the Mostow-Siu examples (1980, dimension 4), the Gromov-Thurston examples (1987), the exotic Farrell-Jones examples (1989), and the three examples of Deraux (2005, dimension 6). Hence, apart from dimensions 4 and 6, every known example of a closed negatively curved Riemannian manifold is homeomorphic to either a hyperbolic one or a branched cover of a hyperbolic one. On the other hand, Charney-Davis strict hyperbolization (1995) produces a rich and abundant class of (non-Riemannian) negatively curved spaces. Charney-Davis hyperbolization builds on the hyperbolization process introduced by Gromov in 1987 and later studied by Davis and Januszkiewicz (1991). But the negatively curved manifolds constructed using the Charney-Davis strict hyperbolization process are very far from being Riemannian because the metrics have large and highly complicated sets of singularities. In three Lectures we will sketch how to remove all the singularities from Charney-Davis hyperbolized manifolds, obtaining in this way a Riemannian strict hyperbolization process. Hence, through this work, we now know that the class of Riemannian negatively curved manifolds is also rich and large. And we can say that, in some sense, Riemannian negative curvature abounds in nature. Moreover we show we can do the Riemannian hyperbolization in a pinched way, that is, with curvature as close to -1 as desired. Here are two of the many direct consequences of Riemannian hyperbolization that we will mention in the Lectures: (1) Every closed smooth manifold is smoothly cobordant to a closed Riemannian manifold with curvatures$\epsilon$-close to -1, for every$\epsilon>0$. (2) Every closed almost flat manifold is a cusp cross section of a finite volume pinched negatively curved manifold. In the first half of Lecture One we will state the main result and its corollaries. In the second half of Lecture One and part of Lecture Two we will introduce three geometric processes: the two-variable warping trick (based on the Farrell-Jones warping trick), warp forcing, and hyperbolic extensions. Also in Lecture Two we will discuss the construction of extremely useful differentiable structures: normal differentiable structures on cubical manifolds and on Charney-Davis hyperbolizations. Finally in Lecture Three we will sketch how to smooth metrics on hyperbolic cones and sketch how smooth Charney-Davis hyperbolized manifolds. ### Algebraic Geometry and Hyperbolic Geometry - New Connections 2013-06-16 through 2013-06-22 Cabo Frio, Rio de Janeiro; Brazil Meeting Type: conference Subject Area: algebraic geometry Contact: see conference website ### Description This conference is supported by the National Science Foundation and by IMPA.

A closed random flight is a polygon in space. This means that the global geometry and topology of polygon spaces is highly relevant to the statistical geometry of random space polygons and hence to the statistical physics of polymers in solution. This year's Georgia Topology Conference is dedicated to exploring that connection, bringing together researchers working on the symplectic and algebraic geometry of polygon spaces with researchers interested in random polygons and random walks and their applications to biology and physics. The conference runs from July 8-12 in Athens, GA. Travel support is available through a grant from the National Science Foundation.

The Centenary Conference will be held in the city of his birth July 22-26, 2013. The intention is to cover all the areas of Eilenberg's great contributions: topology, category theory and computability. The categorical viewpoint developed by Eilenberg and his collaborators lies behind many recent developments, thus the conference will be of relevance to a large body of current research in mathematics. The program of the Conference will consist of plenary lectures and contributed talks covering the wide scope of Eilenberg's mathematical legacy. Some historical materials will be presented to illustrate social context of his life. The conference venue will be the old campus of the University of Warsaw, Alma Mater of Samuel Eilenberg. Already as a student Eilenberg was one of the most active members of the Warsaw topology group - he left Warsaw in April 1939, thus escaping the Holocaust. After several short employments at institutions in the USA, in 1947 Eilenberg settled at Columbia University, where he stayed until retirement in 1982. He was a member of the Polish and American Mathematical Societies and of the Polish Academy of Sciences. Samuel Eilenberg was an extraordinary personality; he was also a famous collector and expert in Southeast Asian art. He donated his impressive collection to the Metropolitan Museum of Art in New York. The Conference is organized by the University of Warsaw, Polish Mathematical Society and the Institute of Mathematics of the Polish Academy of Sciences in collaboration with the American Mathematical Society and Columbia University. On the occasion of the conference a special volume of Fundamenta Mathematicae will appear, the journal in which Eilenberg published many papers, including his first (in 1934) and the last (in 1988) topological papers. At the conference website you can subscribe to the electronic Conference Newsletter. The First Announcement will be distributed later in Fall. ### International Conference and Workshop on Surfaces of Infinite Type 2013-07-29 through 2013-08-02 Centro de Ciencias Matemáticas de la UNAM Morelia; Mexico Meeting Type: conference, workshop Subject Area: geometry Contact: see conference website ### Description This is a satellite activity to the First Mathematical Congress of the Americas (www.mca2013.org).

### Mathematical Structures of Computation - Algebra and Computation workshop

2014-01-20 through 2014-01-24
École Normale Supérieure de Lyon
Lyon; France

Meeting Type: Workshop

Subject Area: algebraic topology, computer science

Contact: see conference website

### Description

This week follows the conferences Operads and Rewriting (Lyon, 2011) and Algebra and Computation (Marseille, 2012), in order to promote the developement of computational methods in algebra and the algebraic formalisation of computation.

Since the eighties, several results (Anick, Squier, Kobayashi, Brown, Dehornoy-Lafont, …) have shown the interest of methods coming from rewriting theory to solve algebraic decision problems or to compute homological invariants. Convergent (confluent and terminating) presentations, and Gröbner bases for linear structures, allow in particular the computation of normal forms and, thus, one can address decision problems (Dehn problems, combinatorics of Coxeter and Artin groups, …) through computational methods.

The week will cover themes including, but not limited to, the following ones: Garside calculus and the study of Artin groups, diagram algebras in representation theory, rewriting methods in operad theory.

### Mathematical Structures of Computation - Directed Algebraic Topology and Concurrency

2014-01-27 through 2014-01-31
École Normale Supérieure de Lyon
Lyon; France

Meeting Type: Workshop

Subject Area: algebraic topology

Contact: see conference website

### Description

Over the past decades there has been an increasing interest in the potential applications of algebraic topology to study concurrency. This new field at the intersection of topology and computer science was started by a series of works which introduced semantics of concurrent programs based on topological spaces, whose points model the states of programs and paths model executions of the program. Since executions of programs always go forward in time, these topological spaces should be equipped with a notion of direction for paths, which requires adapting the usual tools in algebraic topology to this new setting. Two paths which are homotopic (in a directed sense) correspond to two schedulings of a concurrent program which are equivalent in the sense that they give rise to the same results. Starting from this observation, the study of the space of paths up to homotopy in a directed space provides compact representations of the possible schedulings of concurrent programs, in the same way that homotopy (or homology) groups describe in a concise way the essential characteristics of classical topological spaces. This point of view has provided new tools in order to efficiently verify concurrent programs. Another major application of algebraic topology in the study of concurrent programs can be found in the classification of tasks which can be performed by asynchronous concurrent programs, by modeling coherent states of threads using simplicial complexes and drawing conclusions from the study of their geometrical properties.

The goal of this thematic week is to present the latest developments resulting from the interaction between algebraic topology and concurrency theory:

• Directed algebraic topology: definition and comparison of the various models for directed algebraic topological spaces, and mathematical tools in order to study those (fundamental category, category of components, homology), etc.

• Applications of topology to concurrency: efficient verification of concurrent programs, computability of tasks by asynchronous protocols, etc.

### Semantics of proofs and certified mathematics

2014-04-22 through 2014-07-11
Institut Henri Poincaré
Paris; France

Meeting Type: conference

Subject Area: algebraic topology, homotopy type theory, computer science

Contact: see conference website

### Description

After years of steady development, the technology of proof assistants is currently coming to a mature state. As a matter of fact, it is possible today to formalize a non trivial mathematical proof inside a computer, and to check its correctness automatically. This "tour de force" has been recently achieved for the four color theorem, and a certified proof of the classification of finite groups and of the Kepler conjecture are on the way.

These achievements would not have been possible without the rich and active mathematics of formal proofs which emerged in the 1970s at the frontier of logic and computer science, along the Curry-Howard correspondence. This seminal correspondence enables us to understand a logical proof (of a given formula) as a well-behaved program (of a given type). Besides this by now traditional connection between logic and computer science, a number of unexpected connections are currently emerging with other fields of mathematics – this including homotopy theory, higher dimensional algebra, quantum topology, topos theory, functional analysis and operator algebra. Finally, proof assistants have been successfully applied to certify properties of programs written in high-level languages as well as low-level languages, to implement certified compilers, or to establish important security properties of protocols.

The purpose of this thematic trimester is to provide a forum for the extended community of researchers and students in mathematics and in computer science interested in proof assistants, and more generally, in the mathematics of formal proofs. Much care will be devoted during the trimester to train the mathematicians interested to learn and to use the current proof assistants in their work.

### Topology of Torus Actions and Applications to Geometry and Combinatorics

2014-08-07 through 2014-08-11
Daejeon; Korea Sout

Meeting Type: conference

Subject Area: topology

Contact: see conference website

### Description

The main topic of the conference is the interplay of torus actions with topology, geometry, and the combinatorics of manifolds, orbifolds, and algebraic varieties with torus actions. Toric manifolds, symplectic toric manifolds, and quasitoric manifolds illustrate the correspondence between topological and geometric objects with torus actions and, combinatorial objects such as moment polytopes or fans. Moreover, equivariant cohomology theory and homotopy theory play important roles in the study of such topics. The rank of the acting torus is half of the dimension of the space mentioned above, but in this conference the focus is on torus actions of arbitrary rank, and on the correspondence of such spaces with combinatorial objects. Also covered, are geometric objects without torus actions, on which can be associated combinatorial structures such as Okounkov bodies. All those working in the fields of algebaric topology, transformation group theory, toric geometry, symplectic geometry, and combinatorics are encouraged to participate in the conference.

This conference is a satellite conference of ICM 2014, Seoul. One can find the list of all satellite conferences at http://www.icm2014.org/en/program/satellite/satellites .

### Loop spaces in geometry and topology

2014-09-01 through 2014-09-05
Centre Henri Lebesgue
Nantes; France

Meeting Type: conference

Subject Area: algebraic topology

Contact: see conference website

### Description

One-dimensional objects have played a central role in geometry for a long time. From lines in Euclidean spaces to geodesics in Riemannian manifolds, particular classes of real one-dimensional sub-objects of a given space, i.e. loops or paths, have been successfully used as probes for the ambient geometry. At the local level, Riemannian curvature can be classically recovered from the behavior of geodesic paths via the Jacobi equation. At the global level, landmark results such as Morse's development of the calculus of variations in the large (1929), Berger's classification of holonomy groups (1953), Gromoll and Meyer's homological criterion for the existence of infinitely many closed geodesics (1969), or its reinterpretation by Sullivan-Vigué from the viewpoint of rational homotopy theory (1976), have shown deep connections between spaces of loops and analysis, Lie group theory, or topology. From a quite different perspective, string theory considers loops and paths (strings), as well as Riemann surfaces (worldsheets), as the basic building blocks for a unified theory of matter.

On the mathematical side, symplectic geometry appears to be the most natural setup within which real 1-dimensional objects (loops/paths) interact with complex 1-dimensional objects (Riemann surfaces). Gromov's theory of pseudo-holomorphic curves (1985) and its reinterpretation by Floer as a variational theory for the unregularized gradient flow of the symplectic action functional (1987) proved to be a successful tool in order to address the Arnold and Weinstein conjectures (1986, 1979) on the existence of closed orbits/chords for Hamiltonian systems. The geometric structure of compactified moduli space of pseudo-holomorphic curves gives rise to sophisticated algebraic structures, and in particular to various homology theories such as Floer homology, (embedded) contact homology, Seiberg-Witten-Floer homology, ... In all of these theories, one introduces higher products that account for all the non-canonical choices that one needs to make in order to lift an associative product from homology to the chain level. These operations get organized into a differential which is a coderivation on a larger object known to algebraic topologists as the “Bar construction”.

Almost simultaneously and inspired by the algebraic structures encountered in quantum field theory, algebraic topologists have been trying to understand the chain complexes of free loop and path spaces of a manifold. Chas and Sullivan's natural idea of cutting and pasting loops/paths together with considering Poincaré duality for the underlying manifold has led to a plethora of operations and opened a new field known as “string topology”. In parallel to this topological approach, a lot of effort was put into understanding the algebraic structure of “algebraic loop spaces”, modeled as Hochschild complexes of DGAs or categories equipped with further structures that account for Poincaré duality in the topological setting.

The various procedures for assigning a linear object (complex, homology, category...) to a nonlinear object gave rise to rich homotopical structures. There are many striking (algebraic) similarities between the constructions and difficulties encountered in each of the previous three settings. The common desire to reorganize non-canonical choices into higher homotopies and categories has also led to more elegant formulations of geometric and topological statements in terms of derived categories and functors.

We think that the time is ripe to bring together experts and young mathematicians working in these areas. We expect fruitful interactions and hope to harvest inspiration and new ideas. To this end, we intend to have up to 5 three-hours mini-courses accessible to non-experts, followed by a few talks dealing with more recent developments.

### Description

The main focus of this research program will be on the interaction between algebraic topology, commutative algebra, and representation theory. The underlying theme is the use of homological algebra; it serves as a common language making interaction possible and fruitful. This involves, for instance, the use of derived and triangulated categories, and methods from homotopy theory.

The goal of the program is to facilitate broader, and deeper, interaction between researchers from these different fields. To this end, distinguished experts will participate in this program, teaching advanced courses on subjects of current interest. Further activities include workshops and regular seminars, with specific emphasis on opportunities for young researchers to learn new ideas and techniques.​
