On the Feynman-KAC's Formula and Its Applications to Filtering Theory.
Abstract
Let (x(t)) be a Markov process, not assumed to be time homogenous. It is well known that (s(t)bar) = (t, X(t)) is a time homogeneous Markov process. Let A be its generator. The Feynman-Kac's formula for x(t) takes the following form if the equation: (1,1) Av + cv = 0 admits a solution v, then v has the representation, for s < t: (1.2) v(s,Xs) = E v(t,Xt) exp(integral(stat) c(u,Xu)du) sigma(Xs). We prove this under general conditions on (Xt) .
