| چکیده | ||
| This paper investigates a one-dimensional inverse source problem associated with a time-fractional diffusion equation subject to Dirichlet boundary conditions. The primary focus is on analysing the differentiability of the source function and reformulating the inverse problem in terms of the invertibility input-output mapping. The novelty of the study lies in the characterization of these mappings under the Caputo derivative. To obtain approximate solutions we employ a finite difference scheme based on the $L1$ method. Numerical simulations demonstrate the accuracy and reliability of the proposed approach. Improving algorithmic efficiency will also be a focus of our future research. | ||
