Perturbations of Positive Semigroups on AM-Spaces (1607.08070v3)
Published 27 Jul 2016 in math.FA
Abstract: We consider positive perturbations of positive semigroups on AM-spaces and prove a result which is the dual counterpart of a famous perturbation result of Desch in AL-spaces. As an application we consider unbounded perturbations of the shift semigroup.
