This survey paper contains a surprisingly large amount of material and indeed can serve as
an introduction to some of ideas and methods of singular perturbation theory. In continuation …

This work presents a computational approximate to solve singularly perturbed Fredholm
integro-differential equation with the reduced second type Fredholm equation. This problem …

The purpose of this paper is to present a finite difference method for numerical solutions of
singularly perturbed boundary value problem for second order ordinary differential equation …

We consider a uniform finite difference method on an S-mesh (Shishkin type mesh) for a
singularly perturbed semilinear one-dimensional convection–diffusion three-point boundary …

We consider a singularly perturbed one-dimensional convection-diffusion three-point
boundary value problem with zeroth-order reduced equation. The monotone operator is …

The periodical boundary value problem for linear second-order ordinary differential equation
with small parameter by the first and second derivatives is considered. By the method of …

We consider a uniform finite difference method for nonlinear singularly perturbed multi-point
boundary value problem on Shishkin mesh. The problem is discretized using integral …

This article introduces a numerical method to solve a singularly perturbed Fredholm integro-
differential equation of second order with a discontinuous source term. To effectively handle …

This paper purposes to present a new discrete scheme for the singularly perturbed
semilinear Volterra–Fredholm integro-differential equation including two integral boundary …

In this study, we obtain approximate solution for singularly perturbed problem of differential
equation having two integral boundary conditions. With this purpose, we propose a new …
