Robust Numerical Methods for Singularly Perturbed Differential Equations: A Survey Covering 2008–2012

Abstract: We present new results in the numerical analysis of singularly perturbed convection-diffusionreaction problems that have appeared in the last five years. Mainly discussing layer-adapted meshes, we present also a survey on stabilization methods, adaptive methods, and on systems of singularly perturbed equations.

“…Even for a priori error analysis on this problem, we only find some nonconforming method in [27]. For completeness, we refer the readers to the review article [20] by Roos. In this paper, we derive guaranteed a posteriori error estimates for the nonconforming CrouzeixRaviart finite element approximation [9] of problem (1.1). In contrast to the conforming case, there appears the nonconforming term in error analysis.…”

“…It is also well-known [25,27] that solutions to the problem (1.1) may develop layers, whose approximation is the major difficulty of designing high-order, robust numerical schemes. We refer to [39,38] for a comprehensive information on different numerical techniques for (1.1).…”

“…However, the numerical approximation of those equations is a challenging problem, in general, and it is not possible to get reasonable approximations with the standard numerical algorithms. Therefore developing efficient and effective computational methods for solving those problems has been drawing attention of many researchers for several decades [4][5][6][7].…”
