A Posteriori Error Analysis of hp-FEM for singularly perturbed problems [PDF]

open access: yes, 2014
We consider the approximation of singularly perturbed linear second-order boundary value problems by hp-finite element methods. In particular, we include the case where the associated differential operator may not be coercive.

A Combined Renormalization Group-Multiple Scale Method for Singularly Perturbed Problems

open access: yes, 2010
This paper introduces a straightforward method to asymptotically solve a variety of initial and boundary value problems for singularly perturbed ordinary differential equations whose solution structure can be anticipated.

Quasilinear and quadratic singularly perturbed periodic boundary value problem [PDF]

open access: yes, 2000
summary:The problem of existence and asymptotic behavior of solutions of the quasilinear and quadratic singularly perturbed periodic boundary value problem as a small parameter at highest derivative tends to zero is ...

On the method of lines for singularly perturbed partial differential equations [PDF]

open access: yes, 2017
Magister Scientiae - MScMany chemical and physical problems are mathematically described by partial differential equations (PDEs). These PDEs are often highly nonlinear and therefore have no closed form solutions.

Almost Invariant Elliptic Manifolds

open access: yes, 2001
We consider a singularly perturbed Hamiltonian system, which loses one degree of freedom at " = 0. Assume the slow manifold to be normally elliptic. In the case of an analytic Hamilton function it is shown that the slow manifold persists up to an
