Mutation classes of tilde{A}_n-quivers and derived equivalence classification of cluster tilted algebras of type tilde{A}_n

We give an explicit description of the mutation classes of quivers of type \tilde{A}_n. Furthermore, we provide a complete classification of cluster tilted algebras of type \tilde{A}_n up to derived equivalence. We show that the bounded derived category of such an algebra depends on four combinatorial parameters of the corresponding quiver.
