A class of quadrilateral finite elements for the stokes problem
No full textAbstractWe consider a class of approximations by rectangular finite elements for the Stokes problem, with polynomial pressure approximation of degree at most k-1 on each rectangle. We will build an optimal velocity approximation (when both computational cost and accuracy are considered), in order to obtain stable elements
A mixed formulation for 3D magnetostatic problems: theoretical analysis and face-edge finite element approximation
No full textAn hp-analysis of the local discontinuous Galerkin method for diffusion problems
No full textWe present an -analysis of the local discontinuous Galerkin method for diffusion problems, considering unstructured meshes with hanging nodes and two- and three-dimensional domains. Our estimates are optimal in the meshsize and slightly suboptimal in the polynomial approximation order .Perugia, Ilaria; Schotzau, Dominik. (2001).
