Optimal operator preconditioning for pseudodifferential boundary problems

Heiko Gimperlein, Jakub Stocek, Carolina Urzua-Torres

We propose an operator preconditioner for general elliptic pseudodifferential equations in a domain $\Omega$, where $\Omega$ is either in ${\mathbb{R}}^n$ or in a Riemannian manifold. For line…
