Discrete fundamental groups and finite quotients of groups

Jeudi 15 novembre 14:00-15:00 - Thiebout Delabie - Orsay

Résumé : Many examples of metric spaces with particular coarse properties are created using a sequence of Cayley graphs, particularly box spaces which consists of the Cayley graphs of the quotients of a single group by a sequence of finite index normal subgroups.
In order to better understand these box spaces we consider a discrete version of the fundamental group.

Lieu : salle 2L8 (IMO, bâtiment 307)

Notes de dernières minutes : Pour cause d’assemblée générale il n’y aura pas de café culturel.
