Network Communication with operators in Dedekind Finite and Stably Finite Rings [PDF]

open access: yes, 2016
Messages in communication networks often are considered as "discrete" taking values in some finite alphabet (e.g. a finite field). However, if we want to consider for example communication based on analogue signals, we will have to consider messages that

On Reversible Group Rings [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2006
Let G be an arbitrary finite group, R be a finite associative ring with identity and RG be the group ring. We show that ℤ2Q8 is the minimal reversible group ring which is not symmetric, and we also characterise the finite rings R for which RQ8 is reversible. The first result extends a result of Gutan and Kisielewicz which shows that ℤ2Q8 is the minimal

Primitive near-rings [PDF]

open access: yes, 1970
The theory of near-rings has arisen in a variety of ways. There is a natural desire to generalise the theory of rings and skew fields by relaxing some of their defining axioms.

A Note on Skew Generalized Power Serieswise Reversible Property

open access: yesInternational Journal of Analysis and Applications, 2023
The aim of this paper is to introduce and study (S, ω)-nil-reversible rings wherein we call a ring R is (S, ω)-nil-reversible if the left and right annihilators of every nilpotent element of R are equal.

Extensions of i-reversible rings

open access: yesJournal of Algebra and Its Applications, 2023
A ring [Formula: see text] is said to be i-reversible if for every [Formula: see text] [Formula: see text][Formula: see text], [Formula: see text] is a nonzero idempotent implies [Formula: see text] is an idempotent. It is known that the rings [Formula: see text] and [Formula: see text] (the ring of all upper triangular matrices over [Formula: see ...

Foreign bodies inside us - Trends and knowledge regarding long-acting reversible contraceptives (LARCs) use, factors influencing of contraceptives choice-making process, and the dual-method use among Polish college-aged women

open access: yesJournal of Education, Health and Sport, 2023
Introduction: The choice-making process of the contraceptive method seems complex and influenced by many factors. Long-acting reversible contraceptives require mechanical interference with the woman's body. For some, it will be an insurmountable barrier

Images of formal matrices of elements of matrix groups over associative rings

open access: yesНауковий вісник Ужгородського університету. Серія: Математика і інформатика, 2020
The paper substantiates the image by formal matrices of some elements of linear groups over associative rings by using the properties of redundant and fixed modules.

Self dual, reversible and complementary duals constacyclic codes over finite local Frobenius non-chain rings of length 5 and nilpotency index 4.

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021
Over finite local Frobenius non-chain rings of length 5 and nilpotency index 4 and when the length of the code is relatively prime to the characteristic of the residue field of the ring, the structure of the dual of γ-constacyclic codes is established ...

CHARACTERIZATIONS OF t2-REVERSIBLE RINGS

open access: yesSouth East Asian J. of Mathematics and Mathematical Sciences, 2023
This article aims to investigate the ring theoretic structures of (strongly) t2-reversible ring using the concept of non-zero tripotent elements. A ring R is said to be t2-reversible if ab = 0 implies bat2 = 0 for all a,b ∈ R and t is a non-zero tripotent element of R.
