Abstract: The concepts of torsion and torsion-free objects have their origins in abelian group theory, where for an abelian group G the torsion subgroup T(G) of G is defined by T(G) = {x ? G | there exists a positive integer n such that nx = 0}, and where G is torsion-free provided T(G) = 0. Several ways of generalizing these notions to the category RM of left R-modules over a ring are known. In [3] Dickson defines the concept of a torsion theory for certain abelian categories which include RM, and this definition encompasses most of the standard generalizations of torsion and torsion-free in RM. We shall study these torsion theories in RM rather than in the more general setting in which R they originally appeared.
