Occupation Times for Jump Processes

We consider a class of pure jump Markov processes in \rr^d whose jump kernels are comparable to those of symmetric stable processes. We prove a support theorem, a lower bound on the occupation times of sets, and show that we can approximate resolvents using smooth functions
