Kummer theory without roots of unity [PDF]

open access: yes, 1988
We give a description of the group H(R,ZpnZ) of cyclic pn-extensions with normal basis over a connected ring R, assuming that the prime p is a unit in R.

ACCP rises to the polynomial ring if the ring has only finitely many associated primes [PDF]

open access: yes, 2004
Frohn D. ACCP rises to the polynomial ring if the ring has only finitely many associated primes. COMMUNICATIONS IN ALGEBRA. 2004;32(3):1213-1218.We show for a commutative ring R with unity: If R satisfies the ascending chain condition on principal ideals

A Note on a Self Injective Ring [PDF]

open access: yes, 1965
A ring R with unity is called right (left) self injective if the right (left) R-module R is injective [7]. The purpose of this note is to prove the following: Let R be a prime ring with a maximal annihilator right (left) ideal.

Exchange PF-rings and almost PP-rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1989
Let R be a commutative ring with unity. In this paper, we prove that R is an almost PP–PM–ring if and only if R is an exchange PF–ring. Let X be a completely regular Hausdorff space, and let βX be the Stone Čech compactification of X.

Graded I-second submodules

open access: yesDemonstratio Mathematica, 2021
Let G be a group with identity e, R be a G-graded commutative ring with a nonzero unity 1, I be a graded ideal of R, and M be a G-graded R-module. In this article, we introduce the concept of graded I-second submodules of M as a generalization of graded ...

Health‐Related Social Needs in Children With Sickle Cell Disease Are Associated With Worse Health‐Related Quality of Life

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...

Complexity of Ring Morphism Problems [PDF]

open access: yes, 2006
We study the complexity of the isomorphism and automorphism problems for finite rings with unity. We show that both integer factorization and graph isomorphism reduce to the problem of counting automorphisms of rings.

Subrings of I-rings and S-rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
Let R be a non-commutative associative ring with unity 1≠0, a left R-module is said to satisfy property (I) (resp. (S)) if every injective (resp. surjective) endomorphism of M is an automorphism of M.
