Preconditioning the Pseudo-Laplacian for finite element simulation of incompressible flow

In this paper, we investigate the question of the spectrally equivalence of the so-
called Pseudo-Laplacian to the usual discrete Laplacian in order to use hierarchical
preconditioners for this more complicate matrix. The spectral equivalence is shown to
be equivalent to a Brezzi-type inequality, which is fulfilled for the finite element spaces
considered here.
