Abstract

Uncertain heat equation is a type of uncertain partial differential equations driven by Liu processes. This paper proposes a concept of α-path for uncertain heat equation, and shows that the solution of an uncertain heat equation can be represented by a family of solutions of ordinary heat equations. And, a formula is derived to calculate expected value of solution of uncertain heat equation. Moreover, a numerical method is designed to solve uncertain heat equation. Several examples are given to illustrate the efficiency of the numerical method.
