✦ Synopsis


The equivalence of the following conditions on a chain (L) is proved: (1) (L) is algebraic; (2) There is a right chain domain (T) (with identity) such that (L) is isomorphic to the chain of proper two-sided ideals of (T) and all two-sided ideals of (T) are idempotent; (3) (L) is isomorphic to the congruence lattice of a ring (not necessarily with identity). 1993 Academic Press, Inc.
