Uniformly stable rectangular elements for fourth order elliptic singular perturbation problems [PDF]
, 2011 In this article, we consider rectangular finite element methods for fourth order elliptic singular perturbation problems. We show that the non‐ C0 rectangular Morley element is uniformly convergent in the energy norm with respect to the perturbation ...

Levy Approximation of Impulsive Recurrent Process with Semi-Markov Switching [PDF]
, 2009 In this paper, the weak convergence of impulsive recurrent process with semi-Markov switching in the scheme of Levy approximation is proved. Singular perturbation problem for the compensating operator of the extended Markov renewal process is used to ...

Convergence of singular perturbations in singular linear systems
Linear Algebra and its Applications, 1997 A singularly perturbed singular system of differential equations is studied. Sufficient and necessary conditions for convergence are obtained. The criterion is valid both for the homogeneous and for the nonhomogeneous equation if the functions are sufficiently smooth.

Ain Shams Engineering Journal, 2018 In this paper, a mixed finite difference method is proposed to solve singularly perturbed differential difference equations with mixed shifts, solutions of which exhibit boundary layer behaviour at the left end of the interval using domain decomposition.

Multigrid applied to singular perturbation problems [PDF]
The solution of the singular perturbation problem by a multigrid algorithm is considered. Theoretical and experimental results for a number of different discretizations are presented. The theoretical and observed rates agree with the results developed in

A hybrid perturbation Galerkin technique with applications to slender body theory [PDF]
A two step hybrid perturbation-Galerkin method to solve a variety of applied mathematics problems which involve a small parameter is presented. The method consists of: (1) the use of a regular or singular perturbation method to determine the asymptotic ...

A singular perturbation result for a class of periodic-parabolic BVPs
Open MathematicsIn this article, we obtain a very sharp version of some singular perturbation results going back to Dancer and Hess [Behaviour of a semilinear periodic-parabolic problem when a parameter is small, Lecture Notes in Mathematics, Vol. 1450, Springer-Verlag,
