Municipal Liability and Liability of Supervisors: Litigation Significance of Recent Trends and Developments

The purpose of this presentation is to examine two recent Supreme Court decisions, Connick v. Thompson and Ashcroft v. Iqbal with an eye to their impact on how lower federal courts will assess such claims in the wake of new constraints imposed by these cases. The focus of the discussion will be on developments in single-incident liability cases after Connick and supervisory liability claims after Iqbal

Amenability of groups and GG-sets

This text surveys classical and recent results in the field of amenability of groups, from a combinatorial standpoint. It has served as the support of courses at the University of G\"ottingen and the \'Ecole Normale Sup\'erieure. The goals of the text are (1) to be as self-contained as possible, so as to serve as a good introduction for newcomers to the field; (2) to stress the use of combinatorial tools, in collaboration with functional analysis, probability etc., with discrete groups in focus; (3) to consider from the beginning the more general notion of amenable actions; (4) to describe recent classes of examples, and in particular groups acting on Cantor sets and topological full groups
