Entropies and Poisson boundaries of random walks on groups with rapid decay

Benjamin Anderson-Sackaney, Tim de Laat, Ebrahim Samei +1

Let $G$ be a countable group and $\hat{I}¼$ a probability measure on $G$. We build a new framework to compute asymptotic quantities associated with the $\hat{I}¼$-random walk on $G$, using met…
