String Geometry and Loop Spaces

2014-07-28 through 2014-08-01
University of Greifswald
Greifswald; Germany

Meeting Type: Workshop

Subject Area: algebraic topology, differential geometry

Contact: Konrad Waldorf

Description

String geometry is a rather new area of mathematics that combines topology, differential geometry and higher topos theory. String geometry is supposed to provide important foundations for fermionic string theories; in terms of this motivation, string geometry corresponds to a version of spin geometry on loop spaces. This correspondence imposes interesting questions for the geometry and topology of loop spaces, for instance concerning an appropriate index theory on loop spaces.

Our speakers include: Chris Kottke (Northeastern University), Christian Becker (Universität Potsdam), Christian Sämann (Heriot-Watt University Edinburgh), Danny Stevenson* (University of Adelaide), Hisham Sati (University of Pittsburgh), Mahmoud Zeinalian (Long Island University), Martin Olbermann (Ruhr-Universität Bochum), Pedram Hekmati (University of Adelaide), Peter Teichner (MPIM), Scott O. Wilson (CUNY), Ulrich Bunke (Universität Regenburg), Urs Schreiber* (Radboud Universiteit Nijmegen).

If you would like to participate, please register on the workshop's webpage. Registration will be open until June 15, 2014.

Topology of Torus Actions and Applications to Geometry and Combinatorics

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

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

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.

TABLE HOMOTOPY THEORY: structured ring spectra and their invariants

2014-09-03 through 2014-09-05
MIMS, School of Mathematics, University of Manchester
Manchester; UK

Meeting Type: conference

Subject Area: algebraic topology

Contact: Andrew Baker

Description

The theory of highly structured ring spectra has been actively investigated by algebraic topologists since the 1960s, and progress has been especially spectacular over the past two decades. These advances have been driven by the development of symmetric monoidal model categories of spectra, obstruction theories for the existence of multiplicative structures, and computational programmes leading to dramatic new insights and applications. Related activity on model categories and infinity categories has also been important, in terms of developing theoretical background and applicable technology. The themes of the conference involve several important areas of progress since the turn of the millennium, including (co)homological invariants for E_n ring spectra, spaces of units for E-infinity ring spectra, and relevant aspects of the theories of model and infinity categories.

The conference may be able to offer some degree of financial support to participants giving contributed talks, to postgraduate students, and to others unable to cover costs from their own sources.

Funding is provided by The London Mathematical Society, The Edinburgh Mathematical Society, MIMS, and the University of Glasgow.
