Numerical study of self-adjoint singularly perturbed two-point boundary value problems using collocation method with error estimation

Journal of Ocean Engineering and Science, 2018
A numerical treatment for self-adjoint singularly perturbed second-order two-point boundary value problems using trigonometric quintic B-splines is presented, which depend on different engineering applications.

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

Numerical Solution of Singularly Perturbed Delay Differential Equations with Layer Behavior

Abstract and Applied Analysis, 2014
We present a numerical method to solve boundary value problems (BVPs) for singularly perturbed differential-difference equations with negative shift. In recent papers, the term negative shift has been used for delay.

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.

Robust Error Estimation for Singularly Perturbed Fourth Order Problems

Моделирование и анализ информационных систем, 2016
We consider two-dimensional singularly perturbed fourth order problems and estimate on properly constructed layer-adapted errors of a mixed method in the associated energy norms and balanced norms. This paper is a shortened version of [4].
