Non-commuting automorphisms with non-convergent ergodic averages

V. V. Ryzhikov

Lomonosov Moscow State University

Abstract: Austin and independently Huang, Shao, and Ye found examples of pairs of non-commuting automorphisms with non-convergent 2-fold ergodic averages. We propose new examples among Gaussian and Poisson suspensions over specially chosen transformations with invariant sigma-finite measure.

Keywords:   non-convergence of ergodic averages, rank-one transformations, Gaussian and Poisson suspensions, zero entropy.
