Welcome to the AlgTop-Conf List! This is a home for conference announcements in algebraic topology and, more generally, mathematics meetings which may be of any interest to the algebraic topology community.

There are a few other conference lists available, but this list aims to be more complete by allowing anyone at all to add announcements. Rather than use a wiki, announcement information is stored in database format so that useful search functions can be added as the list grows.

Updates 2014-02-16

We've upgraded the AlgTop-Conf software to CakePHP 2.4.5 and PHP 5.4. This involves substantial changes behind the scenes, but (hopefully!) minimal changes to the user interface. If you notice something not working properly, please let Niles know.

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.

Yangians and Quantum Loop Algebras

2014-05-05 through 2014-05-09
University of Texas at Austin
Austin,Texas; USA

Meeting Type: Workshop

Subject Area: geometry

Contact: see conference website

Description

Yangians and quantum loop algebras are two classes of infinite–dimensional quantum groups associated to a complex semisimple Lie algebra. They were first discovered in the mid–80s as symmetries of solvable models in Quantum Statistical Mechanics, specifically the Heisenberg XXX and XXZ spin chains. They have since appeared in a number of different contexts: Nakajima quiver varities, enumerative geometry, 4 and 5–dimensional supersymmetric gauge theories, scattering amplitudes to name a few.

The focus of this workshop will be on the algebraic aspects of these quantum groups, and their applications to solvable lattice models. The goal will be to familiarize the participants with the basics of these models (Yang–Baxter equations, Baxter’s transfer matrix formalism, Bethe Ansatz) and to explain how the Yangian and quantum loop algebra appear naturally. We will then cover their representation theory in some detail, and explain that their finite–dimensional representations form a meromorphic braided tensor category. Finally, we will review some of the recent developments in this area, in particular the construction of a transcendental tensor equivalence between the two representation categories using abelian difference equations.

Participants should plan to each give a one-hour talk at the workshop. Topics for talks will be assigned by Valerio and Sachin, together with the organizers, based on particpant's background and interests. See the list of topics and references.

Algebraic and Geometric Methods in Applied Discrete Mathematics

2014-06-08 through 2014-06-30
AMS
Utah; USA

Meeting Type: conference

Subject Area: geometry, algebra

Contact: see conference website

Description

This research community will introduce young mathematicians to research bridging ``pure'' mathematics and various applications amenable to the analysis of discrete models. Mathematicians trained in areas such as algebra, topology, geometry, and combinatorics are often unaware of the extent to which they are prepared to tackle open problems in fields such as biology, the social sciences, data analysis, and optimization. There is also significant benefit in attacking applied problems from a discrete perspective with algebraic, topological, geometric and/or combinatorial tools.

Math Research Communities are sponsored by the AMS in order to build communities of young researchers. Following an intense, week-long program in the summer, the aim is for continued research interactions leading to publications. The program is open to senior grad students, postdocs, and junior faculty (i.e. those within 2-3 years before or after PhD).

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 .

Meeting Type: conference

Subject Area: algebraic topology

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.

Description

Homotopical algebra, operads and Grothendieck-Teichmüller groups were introduced separately during the second half of the 20th century. Over the past few years, they enjoyed a rich period of development and cross-fertilisation. The purpose of this conference, which will close the ANR HOGT project, is to give a state of the art of the most recent and interesting results in these research fields.

Interactions between Representation Theory, Algebraic Topology and Commutative Algebra

2015-01-07 through 2015-06-30
Centre de Recerca Matemàtica (CRM)
Barcelona; Spain

Meeting Type: Research program

Subject Area: algebraic topology, representation theory, commutative algebra

Contact: see conference website

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.​

Analysis and Geometry in Metric Spaces

2015-04-01 through 2015-06-30
ICMAT
Madrid; Spain

Meeting Type: Trimester

Subject Area: Analysis and Geometry

Contact: see conference website

Description

We are organizing a series of activities at ICMAT which will bring together a number of first rank specialists in this growing trend. They consist of four introductory courses to this subject, a series of seminars and one large workshop. The courses will take place in May 2015, so that non-specialists interested in learning something about this new field will be more prepared to face the subsequent workshop (from June 1st to June 5th). This will serve as a platform to launch a number of specialized seminars in June. There will also be a few seminars (or a less specialized character) in April.

The organization will offer a number of grants for young researchers covering accomodation for 6 weeks, including the introductory courses and the workshop.
