Resumen:
We consider the Stokes equations in a particular cuspidal domain in R^2. Durán and López García have proved the well-posedness of the problem in suitable weighted Sobolev spaces. In this article, we analyze thenonconforming finite element discretization for this problem given by Crouzeix and Raviart. We establish a mild condition on the meshes which guarantees the stability of the discrete problems.
