Distributionally chaotic families of operators on Fréchet spaces

Abstract

The existence of distributional chaos and distributional irregular vectors has been recently considered in the study of linear dynamics of operators and C0-semigroups. In this paper we extend some previous results on both notions to sequences of operators, C0-semigroups, C-regularized semigroups, and $\alpha$-times integrated semigroups on Fr echet spaces. We also add a study of rescaled distributionally chaotic C0-semigroups. Some examples are provided to illustrate all these results.
