Let (P t ) t 0 and (P t ) t 0 be two diffusion semigroups on R d (d 2) associated with uniformly elliptic operators L={ } (A{) and L ={ } (A {) with measurable coefficients A=(a ij ) and A =(a~i j ), respectively. The corresponding diffusion kernels are denoted by p t (x, y) and p~t(x, y). We derive
