Abstract:

In this paper, we consider the nonlinear backward heat equation, which is severely ill-posed in the sense that the solution does not depend continuously on the data. A Fourier regularization method is proposed to solve this problem. For the regularization solution, the Hölder type stability estimate between the regularization solution and the exact solution is given.

Key words: Backward heat equation, Nonlinear ill-posed problem, Fourier truncation method, Error estimate
