random walks with bounded first moment on finite volume spaces
abstract:
we consider a finite volume homogeneous space endowed with a random walk whose driving measure is zariski-dense. in the case where jumps have finite exponential moment, eskin-margulis and benoist-quint established recurrence properties for such a walk. i will explain how their results can be extended to walks with finite first moment. the key is to make sense of the following claim: "the walk in a cusp goes down faster that some iid markov chain on r with negative mean". joint work with n. de saxcé.
