An implicit finite difference approximation for the solution of the diffusion equation with distributed order in time
Electronic transactions on numerical analysis, Tome 44 (2015), pp. 289-305
In this paper we are concerned with the numerical solution of a diffusion equation in which the time derivative is of non-integer order, i.e., in the interval $(0,1)$. An implicit numerical method is presented and its unconditional stability and convergence are proved. Two numerical examples are provided to illustrate the obtained theoretical results.
