报告简介:

In this talk, we discuss dynamical systems which have bounded complexity with respect to various semi-metrics. First we show that a system has discrete spectrum if and only if it has bounded complexity with respect to some semi-metrics for amenable group actions. Second we show that a system is rigid if and only if it has bounded complexity with respect to some other metrics.
