%L acta75856 %P 571-594 %D 2021 %X In this paper, we consider positive DeschâSchappacher perturbations of bi-continuous semigroups on AM-spaces with an additional property concerning the additional locally convex topology. As an example, we discuss perturbations of the left-translation semigroup on the space of bounded continuous functions on the real line and on the space of bounded linear operators. %N 3-4 %C Szeged %V 87 %A Budde Christian %K AnalĂzis - matematikai %O Bibliogr.: p. 591-594. ; ĂśsszefoglalĂĄs angol nyelven %T Positive Desch-Schappacher perturbations of bi-continuous semigroups on AM-spaces %J Acta scientiarum mathematicarum
