A Numerical Method on Graded Meshes for Caputo Time-Fractional Subdiffusion Equation with Singular Source Term

In this paper, we propose an efficient numerical method to solve initial-boundary value problems of Caputo fractional subdiffusion equations with a class of source terms weakly singular in time. To do this, we firstly derive fractional Volterra integro-differential equations equi...
