1.haut de la page[ID=174106]Non-Abelian Fundamental Groups in Arithmetic Geometry
20 Jul 2009 → 18 Dec 2009; Cambridge, Royaume-Uni
Organisateur: Isaac Newton Institute for Mathematical Sciences

Résumé: In the 1980's Grothendieck formulated his anabelian conjectures that brought to an hitherto-unexplored depth the interaction between topology and arithmetic. This suggested that the study of non-abelian fundamental groups could lead to a new understanding of deep arithmetic phenomena, including the arithmetic theory of moduli and Diophantine finiteness on hyperbolic curves. A certain amount of work in recent years linking fundamental groups to Diophantine geometry intimates deep and mysterious connections to the theory of motives and Iwasawa theory, with their links with arithmetic problems on special values of L-functions such as the conjecture of Birch and Swinnerton-Dyer. The goal of this programme is to investigate the ideas and problems of anabelian geometry within the global context of mainstream arithmetic geometry.

6.haut de la page[ID=305652]Computer Methods for L-functions and Automorphic Forms
22 Mar 2010 → 26 Mar 2010; Université de Montréal, Canada

Résumé: For years, computers have also played a key role in investigating the most central questions in the analytic theory of automorphic forms such as the existence of Maass wave forms. Recently, a team of researchers, including M. Rubinstein (Waterloo) and W. Stein (Seattle), has embarked on an ambitious collaborative effort to systematically gather vast amounts of data concerning, among other things, automorphic forms on higher rank groups. This effort is part of a three year (2008-2011) NSF funded Focused Research Group (FRG) grant dealing with L-functions and automorphic forms. The FRG effort is sure to generate challenges and new questions for people working both on the theoretical and the experimental side of the subject, as well as gathering valuable data that will be precious in suggesting conjectures or revealing new lines of enquiry.

9.haut de la page[ID=281805]Geometry, Topology, and Dynamics of Character Varieties
18 Jui 2010 → 15 Aou 2010; National University of Singapore, Singapour

Résumé: This program concerns character varieties of representations in a Lie group G of a discrete group $\pi$, for example, the fundamental group of a surface. These varieties have rich geometry and are related to interesting topological objects such as locally homogeneous geometric structures on manifolds, and moduli spaces arising in gauge theory. When $\pi$ is the fundamental group of a surface group S, the mapping class group acts with a complicated and mysterious dynamics.

Résumé: This workshop will be devoted to the study of a variety of topics in geometric and asymptotic group theory, with special emphasis on statistical methods and their applications (in theoretical cryptography). We have contributed to the organization of three similar conferences: in Manresa (Spain) in 2006, in Dortmund (Germany) in 2007, in New York in March 2008. We plan to gather leading specialists in various aspects of geometric, asymptotic, and algorithmic group theory. More specifically, the workshop topics will include quasi-isometries, isoperimetric functions, function growth, asymptotic invariants, random walks, algorithmic problems, etc.

14.haut de la page[ID=305642]Topics in Algorithmic and Geometric Group and Semigroup Theory
23 Aou 2010 → 27 Aou 2010; Université de Montréal, Canada

Résumé: During the past 20 years, geometric group theory has developed many different facets, including relations with geometry, topology, analysis, and logic. The new, more geometric, perspectives have enabled rapid progress on many of these fronts. A tremendous solidification of previously disparate results has also occurred. In algorithmic group theory, in recent years, more and more interconnections between computer science and classical group and semigroup theory have been discovered. Automata theory has motivated the definition of new classes of groups, for instance, automaton groups and automatic groups. Techniques from rewriting theory, data compression, and automata theory are used in order to solve more efficiently word problems as well as other computational problems in (semi)group theory. The program of the workshop will capitalize on this recent surge of activity in both areas.

16.haut de la page[ID=305257]Group Actions and Dynamics
04 Oct 2010 → 09 Oct 2010; Université de Montréal, Canada

Résumé: In his seminal book 'Trees', Serre laid down the fundamentals of the theory of groups acting freely on simplicial trees. In the following decade Serre's novel approach unified several geometric, algebraic, and combinatorial methods of group theory into a unique powerful tool, known today as Bass-Serre Theory. Topologists became interested in R-trees with the work of Morgan and Shalen (1985) which generalized parts of Thurston's Geometrization Theorem. A joint effort of several researchers culminated in a description of finitely generated groups acting freely on R-trees, which is now known as Rips' theorem. The key ingredient of the theory is the so-called 'Rips machine'. The idea of the Rips machine comes from Makanin's algorithm (or elimination process) for solving equations in free groups.

17.haut de la page[ID=305650]Equations and First-order Properties in Groups
11 Oct 2010 → 15 Oct 2010; Université de Montréal, Canada

Résumé: Solving equations is one of the main topics in mathematics. A more general and more difficult problem is to describe which formulas of the first-order logic hold in a given group. Recent works on the Tarski's problems (Kharlampovich, Miasnikov, Sela) opened a new direction of research called now 'Algebraic geometry over groups'. We are going to discuss some methods and techniques used for the solution of these problems, and developments in the algebraic geometry for groups, Lie Algebras, and other algebraic systems.
