A quasi-reversibility method for solving a two-dimensional time-fractional inverse heat conduction problem

In this paper, we consider a two-dimensional time-fractional inverse heat conduction problem, which is severely ill-posed. A quasi-reversibility method is proposed to solve this problem with disturbed boundary value. We give the selection of regularization parameters of quasi-reversibility method both under a priori and a posteriori rules, and give the proof of error estimates between the exact solution and its regularization approximation. Further more, numerical results are included to verify the effectiveness of the proposed method. (c) 2023 International Association for Mathematics and Computers in Simulation (IMACS).
