Fixed and Residual Modules

open access: yesНауковий вісник Ужгородського університету. Серія: Математика і інформатика, 2017
The article deals with the properties of fixed and residual endomorphism submodules of modules over arbitrary associative rings with 1. It is shown how they can be used to represent formal matrices images of group homomorphisms generated by elementary ...

Ring of Endomorphisms and Modules over a Ring

open access: yesFormalized Mathematics, 2022
Summary We formalize in the Mizar system [3], [4] some basic properties on left module over a ring such as constructing a module via a ring of endomorphism of an abelian group and the set of all homomorphisms of modules form a module [1] along with Ch. 2 set. 1 of [2].

Constructing Homomorphism Spaces and Endomorphism Rings [PDF]

open access: yes, 2001
We present a new deterministic algorithm for constructing homomorphism spaces and endomorphism rings of finite-dimensional modules. The modules are given via vertex projective presentations over path algebras and finite-dimensional quotients of path ...

Some annihilator ideals in skew Hurwitz series rings [PDF]

open access: yesMathematica Bohemica
A ring $R$ has right (left) property (A) if for every finitely generated two-sided ideal $I\subseteq Z_l(R)$ $(I\subseteq Z_r(R))$, there exists nonzero $u\in R$ $(v\in R)$ such that $Iu=0$ $(vI=0)$. In this article, we establish a relationship between a

On commutative endomorphism rings [PDF]

open access: yesPacific Journal of Mathematics, 1970
This note deals with a finitely generated faithful module E over a commutative semi-prime noetherian ring R, with commutative endomorphism ring HomJ2(Er, E) = Ω(E). It is shown that E is identifiable to an ideal of R whenever Ω(E) lacks nilpotent elements; a class of examples with Ω(E) commutative but not semi-prime is discussed.

On Group Codes Over Elementary Abelian Groups

open access: yesSultan Qaboos University Journal for Science, 2003
For group codes over elementary Abelian groups we present definitions of the generator and the parity check matrices, which are matrices over the ring of endomorphism of the group.

Computing global dimension of endomorphism rings via ladders [PDF]

open access: yes, 2016
This paper deals with computing the global dimension of endomorphism rings of maximal Cohen–Macaulay (=MCM) modules over commutative rings. Several examples are computed.

Gorenstein Endomorphism Rings on Curve Singularities [PDF]

open access: yes, 2022
We characterize the Gorensteinness of endomorphism rings of a fractional ideal on a curve singularity by stability of the ideal and a condition on its value semigroup ideal.

Trace Ideals, Normalization Chains, and Endomorphism Rings [PDF]

open access: yes, 2020
In this paper we consider reduced (non-normal) commutative noetherian rings R.With the help of conductor ideals and trace ideals of certain R-modules we deduce a criterion for a reflexive R-module to be closed under multiplication with scalars in an ...
