摘要：Let H be a hereditary artin algebra of finite representation type. We first determine all hammocks in the Auslander-Reiten quiver  Γ(modH）of the category modH of finitely generated left H-modules. This enables us to obtain an effetive method to construct Γ(modH） by simply viewing the ext-quiver of H. As easy applications, we compute the numbers of non-isomorphic indecomposable objects in modH and the associated cluster category C(H),  as well as the nilpotencies of the radicals of modH,   D^b(modH) and C(H).
