Periodic homogenization of discontinuous Markov processes

In this talk, I will present some recent results on homogenization of discontinuous Markov processes with Levy type generators in periodic media. Under a proper scaling, the scaled Markov process is shown to converge weakly to a Levy process. Different phenomena occur depending on the tails of the jumping kernel of the discontinuous Markov process. These results can be viewed as the non-local counterparts of the celebrated work of Bensoussan-Lions-Papanicoaou and Bhattacharya for diffusions.
