The Crouzeix-Raviart Element for non-conforming dual mixed methods: A Priori Analysis
Tomás P. Barrios, J. Manuel Cascón, Andreas Wachtel
Under some regularity assumptions, we report an a priori error analysis of a dG scheme for the Poisson and Stokes flow problem in their dual mixed formulation. Both formulations sa…

The inf-sup stability of the lowest order Taylor-Hood pair on Anisotropic Meshes
Gabriel R. Barrenechea, Andreas Wachtel
Uniform LBB conditions are desirable to approximate the solution of Navier-Stokes, Oseen, and Stokes equations on anisotropic meshes and to enable anisotropic refinements. We prove…
