Undergraduate students of mathematics, physics and engineering wishing to get adept in numerical solutions of boundary value problems with finite difference method will be. In this paper, we consider few numerical methods for singularly perturbed boundary value problems developed by numerous researchers between 2006 to 2013. A Summary of the result of some recent methods is presented and this leads to conclusion and recommendations regarding methods to use on singular perturbation problem. Mathematics, an international, peer-reviewed Open Access journal. Dear Colleagues, The study of the existence, nonexistence, and the uniqueness of solutions of boundary value problems, coupled to its stability, plays a fundamental role in the research of different kinds of differential equations ordinary, fractional, and partial. singularly perturbed problems in one- and two-dimensions. •The proof of robustness and optimal convergence is achieved due to the results of Roos & Linß 1999. •Numerical experiments indicate that the proposed method slightly‘outperforms’ other equally robust and uniformly convergent methods.

PUBLISHER: Basel, Switzerland; Boston [Mass.]: Birkhäuser Verlag, c2007. SERIES: International series of numerical mathematics, v. 156. Feb 17, 2018 · The nonlinear boundary value problem BVP formulated in the present work is the limit of the diffusion-reaction problem with a reaction parameter tending to infinity. To solve numerically the singularly perturbed diffusion-reaction problem, monotone approximations are employed. In this paper, a class of systems for epidemic contagion is considered. An epidemic virus ecological model is described. Using the generalized variation iteration method, the corresponding approximate solution to the nonlinear system is obtained and the method for this approximate solution is pointed out. The accuracy of approximate solution is discussed, and it can control the epidemic virus.
