A Layer-Adapted Numerical Method for Singularly Perturbed Partial Functional-Differential Equations

Axioms
This article describes an effective computing method for singularly perturbed parabolic problems with small negative shifts in convection and reaction terms. To handle the small negative shifts, the Taylor series expansion is used.

Critical Threshold and Stability of Cluster Solutions for Large Reaction-Diffusion Systems in R [PDF]

, 2002
We study a large reaction-diffusion system which arises in the modeling of catalytic networks and describes the emerging of cluster states. We construct single cluster solutions on the real line and then establish their stability or instability in

Almost Invariant Elliptic Manifolds

, 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
