热传导方程Robin系数反问题解的唯一性及正则化解的存在性
Uniqueness of solution to inverse problem for the Robin coefficient in heat conduction equation and existence of its regularized solution
摘要
Abstract
The Robin coefficient characterizes the heat exchange on the edge of the heat conduction region in the heat conduction model,which is a very important parameter.This article discussed the inversion problem of the Robin coefficient in the heat conduction model based on temperature measurements during a certain period of time.Firstly,the uniqueness result of the solution to the inverse problem was given under certain conditions of boundary and measured values.Then,based on Tikhonov's regularization idea,the objective functional was constructed,and the inverse problem was transformed into finding the minimum of the objective functional,and the existence of minimizer was proved.关键词
