Loop spaces in geometry and topology

Centre Henri Lebesgue

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.

STABLE 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.

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.​

Computations in Groups and Algebras (CoGrAl2015)

2015-02-16 through 2015-02-19
Friedrich Schiller University Jena
Jena, Thuringia; Germany

Meeting Type: Workshop

Subject Area: Cohomology

Contact: see conference website

Description

The aim of the workshop is to shed some light on various aspects of modern finite group theory, with a particular view towards computations. More precisely, we will focus on the following strongly interconnected topics:

(1) Cohomology of finite-dimensional algebras: This generalises the case of finite group algebras, and next to cohomology rings this also covers the computation of Ext algebras. Moreover, aspects from commutative algebra and from topology come into play here.

(2) Fusion systems are a conceptual device to relate the structure of p-groups to their embeddings into arbitrary finite groups, where again topological aspects play a role. In view of (1), the cohomology of p-groups, and how it is influenced by their structure, is particularly interesting in itself, and moreover is one of the cornerstones of computing finite group cohomology in general.

(3) Block theory of finite groups: To understand the structure of module categories deep facts from homology theory are indispensable, yielding tight connections to (1) and complementing the insights acquired there. Moreover, by way of local-global principles, there are intimate connections to (2), leading to mutual influence between these areas.

MSRI
Berkeley, CA; USA

Meeting Type: conference

Subject Area: Differential Geometry

Contact: see conference website

Description

Differential geometry is a subject with both deep roots and recent advances. Many old problems in the field have recently been solved, such as the Poincaré and geometrization conjectures by Perelman, the quarter pinching conjecture by Brendle-Schoen, the Lawson Conjecture by Brendle, and the Willmore Conjecture by Marques-Neves. The solutions of these problems have introduced a wealth of new techniques into the field. This semester-long program will focus on the following main themes: (1) Einstein metrics and generalizations, (2) Complex differential geometry, (3) Spaces with curvature bounded from below, (4) Geometric flows, and particularly on the deep connections between these areas.
