Numerical investigation of singularly perturbed time lag parabolic differential-difference equations

This paper deals with the numerical investigation of a singularly perturbed parabolic differential-difference equation with a time lag. The proposed method comprises the θ method (θ=1) and the non-standard finite difference methods for temporal and spatial variable discretization, respectively. Besi...
