Admissible operators for sun-dual semigroups
arXiv:2408.02150 · doi:10.1007/s00498-025-00430-y
Abstract
We extend classical duality results by Weiss on admissible operators to settings where the dual semigroup lacks strong continuity. This is possible using the sun-dual framework, which is not immediate from the duality of the input and output maps. This extension enables the testing of admissibility for a broader range of examples, in particular for state space of continuous functions or .
