报告摘要：In the theory of dynamical systems, a fundamental problem is to study the asymptotic behavior of dynamical orbits. Lots of different asymptotic behavior have been learned including different periodic-like recurrence such periodic, almost periodic, weakly almost periodic, quasi-weakly almost periodic, Banach periodic etc. We we will talk some related results on these periodic-like recurrences.  As applications: for expanding or hyperbolic dynamical systems, we have proved more than ten different cases of nonrecurrence have dynamical complexity as strong as the dynamical system itself in the sense of topological entropy.
