Abstract

We consider several families of long jump random walks on groups of polynomial volume growth which are naturally expected to have a stable-like behavior. We then prove optimal pseudo-Poincaré inequalities for these walks. These pseudo-Poincaré inequalities allow us to show that the random walks in questions indeed have a stable-like behavior and to obtain detailed estimates.
