Robust stability of linear evolution operators on Banach spaces. (English) Zbl 0817.93055
This paper introduces a stability radius for a wide class of linear infinite-dimensional time-varying systems under structured time-varying perturbations. A framework is presented that allows the same degree of unboundedness in the perturbations as in the generator of the nominal model.
