报告简介:

In this talk I will introduce the notions of (Banach) density- equicontinuity and density-sensitivity. On the equicontinuity side, it turns out that a topological dynamical system is density-equicontinuous if and only if it is Banach density-equicontinuous. On the sensitivity side,I will introduce the notion of density-sensitive tupleand use it to characterize the multi-variant version of density-sensitivity. Moreover, the relation of sequence entropy tuple and density-sensitive tuple both in measure-theoretical and topological setting will also be disscussed.
