Distributional chaos for strongly continuous semigroups of operators
TL;DR: In this article, a sufficient condition for distributional chaos on the point spectrum of the generator of a strongly continuous semigroup is presented, and an application to the semigroup generated in L 2 R by a translation of the Ornstein-Uhlenbeck operator is also given.
Journal ArticleDOI
Hypercyclic Semigroups Generated by Ornstein-Uhlenbeck Operators
TL;DR: In this paper, the chaotic and hypercyclic behavior of the C ≥ 0-semigroups of operators generated by a perturbation of the Ornstein-Uhlenbeck operator with a multiple of the identity in $${L^2(\mathbb {R}^N}) is investigated, depending on the signs of real parts of the eigenvalues of the matrix appearing in the drift of the operator.

Frequently hypercyclic semigroups
TL;DR: In this paper, a sufficient condition for a semigroup to be frequently hypercyclic, whose formulation depends on the Pettis integral, is given, and verified in certain cases in terms of the infinitesimal generator of the semigroup.
Journal ArticleDOI
Trotter-Kato theorems for bi-continuous semigroups and applications to Feller semigroups
TL;DR: In this article, the convergence of bi-continuous semigroups introduced and studied by Kuhnemund was studied and a Lie-Trotter product formula was obtained for Feller semiigroups generated by second order elliptic differential operators with unbounded coefficients.

Frequently hypercyclic semigroups
TL;DR: In this article, a sufficient condition for a semigroup to be frequently hypercyclic, whose formulation depends on the Pettis integral, is given, and this criterion can be verified in certain cases in terms of the in- finitesimal generator of semigroup.
