Semi-discretization Difference Approximation for a Cauchy Problem of Heat Equation in Two-dimensional Space

Abstract

" In this paper we consider a semi-descretization difference scheme for solving a Cauchy problem of heat equation in two-dimensional setting. Some error estimates are proved for the semi-descretization difference regularization method which cannot be fitted into the framework of regularization theory presented by Engl, Hanke and Neubauer. Numerical results show that the proposed method works well."
