Finite element approximation of convection–diffusion problems using an exponentially graded mesh
(2016)We present the analysis of an h version Finite Element Method for the approximation of the solution to convection–diffusion problems. The method uses piece-wise polynomials of degree p≥1, defined on an exponentially graded ...

Robust approximation of singularly perturbed delay differential equations by the hp finite element method
(2013)We consider the finite element approximation of the solution to a singularly perturbed second order differential equation with a constant delay. The boundary value problem can be cast as a singularly perturbed transmission ...
