Inverse source problem of time fractional Cahn–Hilliard equation

In this paper, we consider the inverse source problem of the time fractional two-dimensional Cahn–Hilliard equation. As the problem is ill-posed, we give an iterative regularization method to solve it stably and obtain the Hölder error estimates under the a priori and a posteriori parameter choice rules. Finally, numerical implements are given to verify the effectiveness of the proposed reconstruction.
