Radical endomorphisms of decomposable modules
Autor: J. M. Zelmanowitz
Publikováno v: Journal of Algebra. 279:135-146
An element of the Jacobson radical of the endomorphism ring of a decomposable module is characterized in terms of its action on the components of the decomposition. This extends to arbitrary decomposable modules a result previously known only for the

Correspondences of closed submodules
Autor: J. M. Zelmanowitz
Publikováno v: Proceedings of the American Mathematical Society. 124:2955-2960
If N N is an M M -faithful R R -module, then there is an order-preserving correspondence between the closed R R -submodules of N N and the closed S S -submodules of H o m R ( M , N ) Hom_R(M,N) , where S = E n d R M S=End_RM .

Row rank and the structure of matrix subrings
Autor: J. M. Zelmanowitz, M.S Li
Publikováno v: Journal of Algebra. 136:117-131
Subrings of full matrix rings which have positive row or column rank can be approximated by rings of triangular matrices.

On the Endomorphism Ring of a Discrete Module: A Theorem of F. Kasch
Autor: J. M. Zelmanowitz
Publikováno v: Advances in Ring Theory ISBN: 9781461273646
Using results from the monograph of Mohamed and Mueller on discrete modules, it is shown that the endomorphism ring of a discrete module, modulo its radical, is a direct product of full linear rings.

A Class of Modules with Semisimple Behavior
Autor: J. M. Zelmanowitz
Publikováno v: Abelian Groups and Modules ISBN: 9789401041980
Weakly semisimple modules were introduced in [11] as a simultaneous generalization of semisimple modules and of monoform compressible modules. A principal goal of this paper is to show that the quasi-injective hull of a weakly semisimple module, when
