Fourier Truncation Regularization Method for a Time-Fractional Backward Diffusion Problem with a Nonlinear Source
In present paper, we deal with a backward diffusion problem for a time-fractional diffusion problem with a nonlinear source in a strip domain.We all know this nonlinear problem is severely ill-posed, 7-OH i.e., the solution does not depend continuously on the measurable data.Therefore, we use the Fourier truncation regularization method to solve th
