Singularly perturbed linear boundary value problems

Journal of Mathematical Analysis and Applications, 1992
Two-points boundary value problems are considered for singularly perturbed linear differential systems with multiple parameters. The system is decoupled through a non-singular transformation. Approximate solutions of the original system are found in terms of the solutions of an auxiliary system corresponding to the decoupled one.

Finite-difference method for parameterized singularly perturbed problem

Journal of Applied Mathematics, 2004
We study uniform finite-difference method for solving first-order singularly perturbed boundary value problem (BVP) depending on a parameter. Uniform error estimates in the discrete maximum norm are obtained for the numerical solution.

Parameter uniform numerical method for fourth order singularly perturbed turning point problems exhibiting boundary layers

Ain Shams Engineering Journal, 2018
In this paper, a numerical method based on Shishkin mesh for a singularly perturbed fourth order differential equation with a turning point exhibiting boundary layers is presented. In this method the problem is transformed into a weakly coupled system of

Superconvergence Using Pointwise Interpolation in Convection-Diffusion Problems

, 2013
Considering a singularly perturbed convection-diffusion problem, we present an analysis for a superconvergence result using pointwise interpolation of Gau{\ss}-Lobatto type for higher-order streamline diffusion FEM.
