On the primitive irreducible representations of finitely generated nilpotent groups

open access: yesДоповiдi Нацiональної академiї наук України, 2021
We develop some tecniques whish allow us to apply the methods of commutative algebra for studing the representations of nilpotent groups. Using these methods, in particular, we show that any irreducible representation of a finitely generated nilpotent ...

On separable extensions of group rings and quaternion rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1978
The purposes of the present paper are (1) to give a necessary and sufficient condition for the uniqueness of the separable idempotent for a separable group ring extension RG(R may be a non-commutative ring), and (2) to give a full description of the set ...

Public Key Protocols over Skew Dihedral Group Rings

open access: yesMathematics, 2022
This paper introduces skew dihedral group rings and their applications for public-key cryptography. We present a specific skew group ring that is the underlying algebraic platform for our cryptographic constructions.

Morphic group rings

open access: yesJournal of Pure and Applied Algebra, 2006
An associative ring \(R\) with identity is called left morphic if for every element \(a\in R\) there exists \(b\in R\) such that \(l_R(a)=Rb\) and \(l_R(b)=Ra\), where \(l_R(a)\) denotes the left annihilator of \(a\) in \(R\). The ring \(R\) is said to be strongly left morphic if every matrix ring \(M_n(R)\) is left morphic [\textit{W. K.

On Idempotent Units in Commutative Group Rings

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2020
Special elements as units, which are defined utilizing idempotent elements, have a very crucial place in a commutative group ring. As a remark, we note that an element is said to be idempotent if r^2=r in a ring. For a group ring RG, idempotent units are

Group Rings Satisfying Generalized Engel Conditions

open access: yesپژوهش‌های ریاضی, 2020
Let R be a commutative ring with unity of characteristic r≥0 and G be a locally finite group. For each x and y in the group ring RG define [x,y]=xy-yx and inductively via [x ,_( n+1)  y]=[[x ,_( n)  y]  , y].

On Galois projective group rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
Let A be a ring with 1, C the center of A and G′ an inner automorphism group of A induced by {Uα in ​A/α in a finite group G whose order is invertible}.

Linear groups and group rings

open access: yesJournal of Algebra, 2006
The authors' prime objective is to prove that the integral group ring \(\mathbb{Z} G\) of the non-Abelian finite group \(G\) of order prime to 6 contains two Bass cyclic units that generate a non-Abelian free group. A Bass cyclic unit of \(\mathbb{Z} G\) is an element of the form \[ (1+x+\cdots+x^{k-1})^m+d^{-1}(1-k^m)(1+x+\cdots+x^{d-1}), \] where \(x\

Generalizations of Morphic Group Rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
An element a in a ring R is called left morphic if there exists b∈R such that 1R(a)=Rb and 1R(b)=Ra. R is called left morphic if every element of R is left morphic.
