Identifying initial value problem for time‐fractional diffusion equation with Caputo‐like counterpart hyper‐Bessel operator: Optimal error bound analysis and regularization method
Abstract:In this paper, we consider the inverse problem for identifying the initial value problem for time-fractional diffusion equation with hyper-Bessel operator. Firstly, we show that this problem is ill-posed and analyze the optimal error bound. Next, we use the fractional Landweber iterative regularization method to solve this problem and give the error estimates between the regularization solution and the exact solution under the a priori regularization parameter choice rule and a posteriori regularization parame… Show more
