A novel fitted operator finite difference method for a singularly perturbed delay parabolic partial differential equation (Q621021)

The authors present a robust fitted operator finite difference method for the numerical solution of a singularly perturbed delay parabolic partial differential equation. This method is unconditionally stable and is convergent with order \(\mathcal O(k+h^2)\), where \(k\) and \(h\) are respectively the time and space step-sizes. The performance of the presented method is illustrated through some numerical experiments.
