The Inverse Problem for a Heat Conduction Equation

摘要/Abstract

摘要:

介绍了数理方程反问题的研究现状和主要方法.用Galerkin逼近法和拓扑度理论得出一类线性方程反问题的存在性定理,用不动点原理得出一类非线性方程反问题的存在性、惟一性定理,并给出求解反问题的算法和收敛性证明.

Abstract:

The features and methods of studying inverse problems are introduced. The existence of a linear heat conduction equation is given by Carlerkin approximation method and the theory of topo-logical degree. The existence and uniquenes for the inverse problem of nonlinear equation are shown by using the fixed point theory. An algorithm for solving{u,q} is also given.
