Infinite-time admissibility under compact perturbations

Optimization and Control 2019-04-26 v1

Abstract

We investigate the behavior of infinite-time admissibility under compact perturbations. We show, by means of two completely different examples, that infinite-time admissibility is not preserved under compact perturbations QQ of the underlying semigroup generator AA, even if AA and A+QA+Q both generate strongly stable semigroups.
