The Euler-$\alpha$ equations are a regularization of the incompressible Euler system, obtained by dynamical averaging of small scales. The problem of identifying the limiting behavior of solutions when $\alpha \to 0$ is similar to the analogous problem for vanishing viscosity, but with important differences. In this talk we discuss several results concerning this limit, assuming no-slip boundary conditions and initial data increasingly irregular.
Joint work with Adriana Valentina Busuioc (U. St. Etienne), Dragos Iftimie (U. Lyon) and Helena Nussenzveig Lopes (UFRJ).
