	STUDIA MATHEMATICA - Issue no. 2 / 2009

	Article:	ASSOCIATED CLASSES OF MODULES. Authors: IULIU CRIVEI, SEPTIMIU CRIVEI.


	Abstract: Let C be a non-empty class of modules closed under isomorphic copies. We consider some classes of modules associated to C. Among them, we study two important classes in the theory of natural and conatural classes of modules, namely the class consisting of all modules having no non-zero submodule in C, as well as its dual. Key words and phrases: Class of modules, natural class, conatural class.
