Homogenization of periodic semilinear parabolic degenerate PDEs

摘要

In this paper a second order semilinear parabolic PDE with rapidly oscillating coefficients is homogenized. The novelty of ourresult lies in the fact that we allow the second order part of the differential operator to be degenerate in some part of R~d. Our fully probabilistic method is based on the deep connection between PDEs and BSDEs and the weak convergence of a classof diffusion processes.
