Séminaire OrléansErgodic theory beyond amenable groups

We will give an exposition of a new method of proving ergodic theorems for group actions. This method treats amenable groups and non-amenable groups on an equal footing, and yields, for example, ergodic theorems for general word-hyperbolic group, a class which was inaccessible with previous methods. Based on joint work with Lewis Bowen.
