Abstract
In this paper we show that Dirichlet heat kernel estimates for a class of (not necessarily symmetric) Markov processes are stable under nonlocal Feynman-Kac perturbations. This class of processes includes, among others, (reflected) symmetric stable-like processes in closed d-sets in Rd, killed symmetric stable processes, censored stable processes in C1,1 open sets, as well as stable processes with drifts in bounded C1,1 open sets. These twosided estimates are explicit involving distance functions to the boundary.
