Let $G$ be a locally compact group acting by measure-preserving transformations on a probability space $(X,\mu)$. To every probability measure on $G$ there is an associated averaging operator on $L^p(X,\mu)$. Ergodic theorems describe the pointwise...

Finite models of infinite groups/actions/manifolds are useful for studying spectral and $L^2$-invariants, constructing random processes and have recently been used to introduce new invariants of group actions useful for proving nonembedding and...
