Suppose A is an artinian ring, with indecomposable A-modules {[P.sub.[alpha]] |[alpha] [member of] I} (representatives from each isomorphism class for some index set I).
Suppose R is an artinian ring that is not semisimple and with two additional indecomposable modules [I.sub.1], [I.sub.2] that are not projective and not isomorphic.
Every finitely generated module over a right Artinian ring is [pi]-Rickart (see Theorem 2.30), every free module which its endomorphism ring is generalized right principally projective is [pi]-Rickart (see Corollary 3.5), every finitely generated projective regular module is [pi]-Rickart (see Corollary 3.7) and every finitely generated projective module over a commutative [pi]-regular ring is [pi]-Rickart (see Proposition 3.11).
Let R be a right Artinian ring and M a finitely generated R-module.
Every right Artinian ring is generalized right principally projective.
Let R be a right Artinian ring. Then [M.sub.n] (R) is generalized right principally projective for every positive integer n.

of Wisconsin- Madison) also includes coverage of rarer subjects in this field, including transcendental field extensions, modules over Dedekind domains and artinian rings. Unlike similar textbooks, this volume steers away from chapter-end problems by including full details of all proofs as problems are presented.
