This paper presents an overview of singular perturbations and time scales (SPaTS) in
control theory and applications during the period 2002-2012. The previous …

In this paper, we address a class of boundary layer originated singularly perturbed parabolic
reaction-diffusion problems with Robin boundary conditions having large time delay; for the …

In this paper, a system of time dependent boundary layer originated reaction dominated
problems with diffusion parameters of different magnitudes, is considered for numerical …

In this article, a parameter uniform numerical method is developed for a two-parameter
singularly perturbed parabolic partial differential equation with discontinuous convection …

In this article, we study the problem of determining an appropriate grading of meshes for a
system of coupled singularly perturbed reaction–diffusion problems having 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 …

This work presents a numerical solution to singularly perturbed Robin-type parabolic
convection–diffusion problems. A hybrid method that combines the central difference …

Objectives An accurate exponentially fitted numerical method is developed to solve the
singularly perturbed time lag problem. The solution to the problem exhibits a boundary layer …

This paper deals with the study on system of reaction diffusion differential equations for
Robin or mixed type boundary value problems (MBVPs). A cubic spline approximation has …

Adaptive mesh generation has become a valuable tool for the improvements of accuracy
and efficiency of numerical solutions over fixed number of meshes. This paper gives an …
