Extrapolation spaces and Desch-Schappacher perturbations of bi-continuous semigroups


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. We will also discuss several examples. This talk is based on joint works with B. Farkas.
