In this paper, we prove the local-in-time existence and a blow-up criterion of solutions in the Besov spaces for the Euler-α equations of inviscid incompressible fluid flows in Rd,d≥2. We also establish the convergence rate of the solutions of the Euler-α equations to the corresponding solutions of the Euler equations as the regularization parameter α approaches 0 in R2.
