Abstract

We construct a new Fortin operator for the lowest order Taylor–Hood element which is uniformly stable both in L2 and H1 The construction which is restricted to two space dimensions is based on a tight connection between a subspace of the Taylor–Hood velocity space and the lowest order Nedelec edge element General shape regular triangulations are allowed for the H1stability while some mesh restrictions are imposed to obtain the L2stability As a consequence of this construction a uniform inf–sup condition associated the corresponding discretizations of a parameter dependent Stokes problem is obtained and we are able to verify uniform bounds for a family of preconditioners for such problems without relying on any extra regularity ensured by convexity of the domainKA Mardal was supported by the Research Council of Norway through Grant 209951 and a Centre of Excellence grant to the Centre for Biomedical Computing at Simula Research Laboratory R Winther was supported by the Research Council of Norway through a Centre of Excellence grant to the Centre of Mathematics for Applications
