Abstract: A symmetric error estimate for Galerkin approximations of solutions of the Navier-Stokes equations in two space dimensions plus time is given. The finite-dimensional function spaces are taken to be divergence-free, and time is left continuous. The estimate is similar to known results for scalar parabolic equations. An application of the result is given for mixed method formulations. A short discussion of examples is included. Finally, there are some remarks about a partial extension to three space dimensions.
