Commutativity of one sided s-unital rings through a Streb's result

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
The main theorem proved in the present paper states as follows “Let m, k, n and s be fixed non-negative integers such that k and n are not simultaneously equal to 1 and R be a left (resp right) s-unital ring satisfying [(xmyk)n−xsy,x]=0 (resp [(xmyk)n ...

Poincar\'e series of modules over compressed Gorenstein local rings

open access: yes, 2014
Given positive integers e and s we consider Gorenstein Artinian local rings R of embedding dimension e whose maximal ideal $\mathfrak{m}$ satisfies $\mathfrak{m}^s\ne 0=\mathfrak{m}^{s+1}$.

Minimal irreducible solvable subgroups of the group GL(q,{Z}_{p})

open access: yesНауковий вісник Ужгородського університету. Серія: Математика і інформатика, 2018
All minimal irreducible solvable subgroups of the group GL(q,{Z}_{p}) (q is a prime, {Z}_{p} is the ring of rational $p$-adic integers) are described up to conjugation for p ...

On Certain Divisibility Property of Polynomials [PDF]

open access: yes, 2010
We review the definition of D-rings introduced by H. Gunji & D. L. MacQuillan. We provide an alternative characterization for such rings that allows us to give an elementary proof of that a ring of algebraic integers is a D-ring.

Generalized periodic rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
Let R be a ring, and let N and C denote the set of nilpotents and the center of R, respectively. R is called generalized periodic if for every x∈R\(N⋃C), there exist distinct positive integers m, n of opposite parity such that xn−xm∈N⋂C.

The ring of arithmetical functions with unitary convolution: General Truncations [PDF]

open access: yes, 2002
Let A denote the ring of arithmetical functions with unitary convolution, and let V be a finite subset of the positive integers having the property that for every v in V, all unitary divisors of v lie in V.

Graphs Induced by W-Regular Rings With Application to Zpn

open access: yesInternational Journal of Mathematics and Mathematical Sciences
A ring R is called W-regular if for any non-nilpotent element a of R, there exists an element b of R such that a=aba. This ring is generalized to a regular ring and is a special type of π-regular ring; therefore, some results on rings that are regular ...

On commutativity of one-sided s-unital rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
The following theorem is proved: Let r=r(y)>1, s, and t be non-negative integers. If R is a left s-unital ring satisfies the polynomial identity [xy−xsyrxt,x]=0 for every x,y∈R, then R is commutative. The commutativity of a right s-unital ring satisfying

Relative integral basis for algebraic number fields

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
At first conditions are given for existence of a relative integral basis for OK≅Okn−1⊕I with [K;k]=n. Then the constrtiction of the ideal I in OK≅Okn−1⊕I is given for proof of existence of a relative integral basis for OK4(m1,m2)/Ok(​m3).
