Title: Extrapolation spaces and Desch-Schappacher perturbations of bi-continuous semigroups.

Abstract: We construct extrapolation spaces for non-densely defined (weak) Hille-Yosida operators. In particular, we discuss extrapolation of bi-continuous semigroups. As an application we present a Desch-Schappacher type perturbation result for this kind of semigroups. This talk is based on joint work with B. Farkas.
