## Abstract

In this paper we prove a stochastic representation for solutions of the evolution equation $\partial_t \psi_t= \frac{1}{2}L^\ast \psi_t$ where $L^\ast$ is the formal adjoint of a second order elliptic differential operator L, with smooth coefficients, corresponding to the infinitesimal generator of a finite dimensional diffusion $(X_t)$. Given $\psi_0 = \psi$, a distribution with compact support, this representation has the form $\psi_t = E(Y_t(\psi))$ where the process $(Y_t(\psi))$ is the solution of a stochastic partial differential equation connected with the stochastic differential equation for $(X_t)$ via Ito's formula.
