Singular perturbation problems with turning points arise as mathematical models for various
physical phenomena. The problem with interior turning point represent one-dimensional …

This review paper contains computational methods or solution methodologies for singularly
perturbed differential difference equations with negative and/or positive shifts in a spatial …

In the present paper, a parameter-uniform numerical method is constructed and analysed for
solving one-dimensional singularly perturbed parabolic problems with two small …

An approach to solving coefficient inverse problems for nonlinear reaction-diffusion-
advection equations is proposed. As an example, we consider an inverse problem of …

In this paper, a linear singularly perturbed Fredholm integro-differential initial value problem
with integral condition is being considered. On a Shishkin-type mesh, a fitted finite difference …

We consider the singularly perturbed initial value problem for a linear first order Volterra
integro-differential equation with delay. Our purpose is to construct and analyse a numerical …

In this paper, we deal with a fitted second-order homogeneous (non-hybrid) type difference
scheme for solving the singularly perturbed linear second-order Fredholm integro …

The goal of this study is to introduce a second-order computational method to solve Volterra-
Fredholm integro-differential equations involving boundary layers. To solve numerically, we …

The design and analysis of a finite difference method for solving a class of time-fractional
singularly perturbed convection-diffusion problems is the subject of this paper. The time …

In this paper, the initial value problem for a quasilinear singularly perturbed delay Volterra
integro-differential equation was considered. By the method of integral identities with the use …
