Isogeometric analysis for singularly perturbed problems in 1-D: error estimates
Xenophontos, Christos; Sykopetritou, Irene (2020)We consider one-dimensional singularly perturbed boundary value problems of reaction-convection-diffusion type, and the approximation of their solution using isogeometric analysis. In particular, we use a Galerkin formulation ...

A mixed hp FEM for the approximation of fourth-order singularly perturbed problems on smooth domains
Constantinou, P.; Franz, S.; Ludwig, L.; Xenophontos, Christos (2019)We consider fourth-order singularly perturbed problems posed on smooth domains and the approximation of their solution by a mixed Finite Element Method on the so-called Spectral Boundary Layer Mesh. We show that the method ...
