Abstract: A standard method for proving the inf-sup condition implying
stability of finite element approximations for the stationary Stokes equations
is to construct a Fortin operator. In this paper, we show how this
can be done for Taylor-Hood methods, which use continuous piecewise polynomial
approximations for both velocity and pressure.
