This paper deals with numerical treatment of singularly perturbed parabolic differential
equations having large time delay. The highest order derivative term in the equation is …

In this article, we consider a class of singularly perturbed two-parameter parabolic partial
differential equations with time delay on a rectangular domain. The solution bounds are …

The objective of this work is to provide an efficient and higher-order numerical scheme for
the solution of a singularly perturbed 2D time-delayed parabolic convection-diffusion …

The purpose of this work is to provide robust numerical scheme for singularly perturbed time
delay (large) convection-reaction-diffusion problem with two small parameters. The work …

Purpose The purpose of this work is to introduce an efficient, global second-order accurate
and parameter-uniform numerical approximation for singularly perturbed parabolic …

The objective of this work is to provide a robust numerical scheme for solving a singularly
perturbed semilinear parabolic differential–difference equation having both time delay along …

In this work, we consider the numerical approximation of a two dimensional elliptic singularly
perturbed weakly-coupled system of convection–reaction–diffusion type, which has two …

We investigate in this article convergence for ak th (k≥ 2) order finite element method on a
Bakhvalov-type mesh for a two-parameter singularly perturbed two-point boundary value …

The article contains a survey of publications studying problems characterized by the
presence of fast variables with various rates of change (time scales). We consider the …

This paper aims to establish the finite difference scheme on Bakhvalov-type mesh for the
singularly perturbed pseudo-parabolic problems with time-delay. Using the energy …
