非齐次热传导方程逆时问题的一种正则化方法
A Regularization Method for A Backward Problem of Non-homogeneous Heat Equations
摘要
Abstract
A backward problem of non-homogeneous heat conduction equations is considered, which is a typical ill-posed problem. By the Fourier expansions of the non-homogeneous term and the final temperature w(x,T) , a regularizing approximate problem is constructed, then a regularization solution of the original backward problem is obtained. Furthermore, the error estimates of the stability and the convergence for the regularization solution are presented. Finally, numerical examples are given to show the feasible of the proposed regularization method.关键词
