  摘要：We consider diffusions on R-d or random walks on Z(d) in a random environment which is stationary in space and in time and with symmetric and uniformly elliptic coefficients. We show existence and Holder continuity of second space derivatives and time derivatives for the annealed kernels of such diffusions and give estimates for these derivatives. In the case of random walks, these estimates are applied to the Ginzburg-Landau del phi interface model.
