Stochastic Feynman-kac Equations Associated to Lévy-itô Diffusions

We consider linear parabolic stochastic integro-PDE’s of FeynmanKac type associated to Lévy-Itô diffusions. The solution of such equations can be represented as certain Feynman-Kac functionals of the associated diffusion such that taking expectation yields the deterministic Feynamn-Kac formula. We interpret the problem in the framework of white noise analysis and consider differentiation in the sense of stochastic distributions. This concept allows for relaxed assumptions on the equation coefficients, identically to those required in problems of similar deterministic integro-PDE’s.
