This paper is devoted to the numerical treatment of a class of singularly perturbed delay
boundary value problems with a left layer. The method is proposed based on the …

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

This paper studies the numerical solutions of singularly perturbed parabolic convection–
diffusion problems with a delay in time. We divide the domain using a piecewise uniform …

In this paper, we present a numerical integration method to solve singularly perturbed delay
differential equations. In this method, we first convert the second order singularly perturbed …

In this paper, we have presented a computational method for solving singularly perturbed
delay differential equations with twin layers or oscillatory behaviour. In this method, the …

Recently, the structure, function, stability, and dynamics of subcellular structures, organelles,
and multiprotein complexes have emerged as a leading interest in structural biology …

This paper deals with singularly perturbed boundary value problem for a linear second order
delay differential equation. It is known that the classical numerical methods are not …

In this paper, we present a finite difference method for singularly perturbed linear second
order differential-difference equations of convection–diffusion type with a small shift, ie …

In this paper, we consider a second-order singularly perturbed differential-difference
equations with mixed delay and advance parameters. At first, we approximate the model …

In this paper an exponentially fitted finite difference method is presented for solving
singularly perturbed two-point boundary value problems with the boundary layers. A fitting …
