Critical Functions and Inf-Sup Stability of Crouzeix-Raviart Elements

C. Carstensen, S. Sauter

In this paper, we prove that Crouzeix-Raviart finite elements of polynomial order $p \geq 5$ , $p$ odd, are inf-sup stable for the Stokes problem on triangulations. For $p \geq 4$ , $p$ …

Solvability of Discrete Helmholtz Equations

Maximilian Bernkopf, Stefan Sauter, Céline Torres +1

We study the unique solvability of the discretized Helmholtz problem with Robin boundary conditions using a conforming Galerkin $h p$ -finite element method. Well-posedness of the di…
