Finite-Dimensional Representations constructed from Random Walks

Anna Erschler, Narutaka Ozawa

Given a $1$ -cocycle $b$ with coefficients in an orthogonal representation, we show that any finite dimensional summand of $b$ is cohomologically trivial if and only if $\| b(X_n) \…

Almost invariance of distributions for random walks on groups

Anna Erschler

We study the neighborhoods of a typical point $Z_{n}$ visited at $n$ -th step of a random walk, determined by the condition that the transition probabilities stay close to $μ^{*n}(Z_n…
