Abstract
This paper is concerned with linear uniformly elliptic and parabolic partial
differential equations in divergence form. It is assumed that the coefficients
of the equations are random variables, constant in time. The Green's functions
for the equations are then random variables. Regularity properties for
expectation values of Green's functions are obtained. In particular, it is
shown that the expectation value is a continuously differentiable function
whose derivatives are bounded by the corresponding derivatives of the heat
equation. Similar results are obtained for the related finite difference
equations.
