WebTheorem 1 (Feynman-Kac Formula) Let Xt be a diffusion satisfying SDE (1). If there is a solution to PDE (3) with the boundary condition (2), then the solution is unique and the solution is: t (x C x t E e g t, R u du 4) This theorem establishes a distinguished link between the analytical theory of PDEs and the probability theory relevant to SDEs.
