On the perturbation of positive semigroups

Functional Analysis 2016-06-28 v1

Abstract

We prove a perturbation result for positive semigroups, thereby extending a heat kernel estimate by Barlow, Grigor'yan and Kumagai for Dirichlet forms (\cite{bgk2009}) to positive semigroups. This also leads to a generalization of domination for semigroups on LpL_p-spaces.
