CONFERENCE
GAGTA-9 : Geometric, Asymptotic and Combinatorial Group Theory and Applications
September 14 -18, 2015
September 14 -18, 2015
The series of conferences named "GAGTA" is devoted to the confrontation of several viewpoints on the theory of infinite groups: geometric, combinatorial, asymptotic and probabilistic, algorithmic and computational. Topics discussed at these conferences include group actions; growth and isoperimetric functions and other asymptotic invariants; random walks; algebraic geometry on groups; algorithmic properties and their complexity; generic properties and more generally generic complexity; and applications of group theory, notably to non-commutative cryptography.
All these topics place the GAGTA conferences at a meeting point between algebra, topology and geometry, and more and more frequently, at a meeting point also with probability theory and asymptotic methods. Many of the topics discussed at these conferences have deep roots in the classical theory of groups and especially its links with geometry. We can cite also, among the results or the theories that have played an important role in the genesis of the GAGTA conferences, M. Gromov’s results at the beginning of the 1980s, the solution of Tarski’s problem by Z. Sela and by A. Miasnikov and O. Kharlampovich, and more recently the theory of relatively hyperbolic groups developed by M. Gromov, Yu. Ol’shanskii, D. Osin and other mathematicians. The 2015 edition of the conference, the ninth GAGTA and the first to be held in France, will of course rely on the fundamentals of the series; but it will additionally give a special emphasis to the contributions of asymptotic theory; the algorithmic aspects of group theory; and its connections with computer science. |
