Derived equivalences for tame weakly symmetric algebras having only periodic modules. (Q1414683)

Let \(K\) be an algebraically closed field. One of the main results of the paper is a classification, up to derived equivalence, of weakly symmetric finite-dimensional \(K\)-algebras \(A\) that have tame representation type, admit simply connected Galois coverings and all of whose indecomposable modules of finite dimension are periodic. A set of pairwise nonisomorphic representatives of the derived equivalence classes of these algebras is presented.
