✦ Synopsis


Let R be a ÿnite-dimensional algebra over an algebraically closed ÿeld K. One of the main aims of this paper is to prove that if the algebra R is loop-ÿnite or R is strongly simply connected then the following three conditions are equivalent: (a) the algebra R is of inÿnite representation type, (b) the category mod(R) of ÿnitely generated right R-modules contains a full and exact subcategory equivalent with the category of Kronecker modules, (c) every K-algebra A is isomorphic to a K-algebra of the form EndR(X ), where X is a right R-module.
