Abstract :
In this paper we study abstract elementary classes of modules. We give several characterizations of when the class of modules A with Ext i ( A , N ) = 0 (for fixed N and all i ) is abstract elementary class with respect to the notion that M 1 is a strong submodel M 2 if the quotient remains in the given class.
