[PDF] Quasi-similarity and joining-stable invariants of ergodic actions-论文阅读讨论-ReadPaper

摘要

Answering Vershik's question we show that quasi-similarity does not conservethe entropy, proving quasi-similarity of all Bernoulli actions of the groupswith an element of infinite order. We produce joining-stable invariantsconsidering zero $P$-entropy systems and prove an analog of Pinsker's theoremestablishing the disjointness of such systems with the actions of comletelypositive $P$-entropy. Then we apply Poisson suspensions to get a class of thecorresponding examples.
