We shall see, for instance, that local rings are connected with the problem of the uniqueness of Krull-Schmidt decompositions, and that semilocal rings are connected with the problem of “cancellation” of modules.

When we move from commutative rings to noncommutative rings, an alternative way of generalizing an “elemenwise” condition should be to replace the role of elements by that of ideals. By making these changes judiciously in the basic definitions, we are led ι the notions of ., and (..
