Escaping a neighborhood along a prescribed sequence in Lie groups and Banach algebras
Catalin Badea, Vincent Devinck, Sophie Grivaux
It is shown that Jamison sequences, introduced in 2007 by Badea and Grivaux ([C. Badea and S. Grivaux, Unimodular eigenvalues, uniformly distributed sequences and linear dynamics,…
Universal Jamison spaces and Jamison sequences for -semigroups
Vincent Devinck
An increasing sequence of positive integers is said to be a Jamison sequence if the following property holds true: for every separable complex Banach space and…
Strongly mixing operators on Hilbert spaces and speed of mixing
Vincent Devinck
We investigate the subject of speed of mixing for operators on infinite dimensional Hilbert spaces which are strongly mixing with respect to a nondegenerate Gaussian measure. We pr…
Jamison sequences in countably infinite discrete abelian groups
Vincent Devinck
We extend the definition of Jamison sequences in the context of topological abelian groups. Then we study such sequences when the abelian group is discrete and countably infinite.…
