Title: An asymptotic theory for randomly-forced discrete heat equations

Abstract: Stochastic heat equations are a family of fundamental stochastic processes that arise in a variety of scientific settings. In this talk, I describe these equations in a completely-discrete setting, derive them from a simple particle picture, and say some things about their moments' Liapounov exponent[s], if and when a solution exists. This is joint work with M. Foondun.
