Combinatorics of finite-index subgroups
Combinatoire des sous-groupes d’indice fini[su_spacer size= »10″]
[su_spacer size= »10″]
This workshop is dedicated to recent innovations in the quantitative study of finite-index subgroups in discrete groups. In particular :

Stability of permutation almost-representations of a group;
Subgroup growth;
Benjamini–Schramm convergence of random Schreier graphs beyond free groups;
Fine spectral properties of such graphs.

We aim at finding generalisations to wider classes, and applications of recent results.

The workshop will take place at Institut Henri Poincaré, room 201.
