On the structure of the Schur complement matrix for the Stokes equation

Vladislav Pimanov, Ekaterina Muravleva, Ivan Oseledets +1

In this paper, we investigate the structure of the Schur complement matrix for the fully-staggered finite-difference discretization of the stationary Stokes equation. Specifically,…
