摘要
In this paper a simple and convenient new regularization method for solving backward heat equation-Fourier regularization method is given. Meanwhile, some quite sharp error estimates between the approximate solution and exact solution are provided. A numerical example also shows that the method works effectively. (C) 2006 Elsevier Inc.
