Resumen:
Let A be a finite dimensional algebra over an algebraically closed field such that any oriented cycle in the ordinary quiver of A is zero in A. Let T (A) be the trivial extension of A by its minimal injective cogenerator D(A). We characterize, in terms of quivers and relations, the algebras A´ such that T(A) is isomorphic to T(A´).
