Smarandache Non-Associative (SNA-) rings [PDF]

open access: yes, 2005
In this paper we introduce the concept of Smarandache non-associative rings, which we shortly denote as SNA-rings as derived from the general definition of a Smarandache Structure (i.e., a set A embedded with a week structure W such that a proper subset ...

Weakly quadratent rings

open access: yesJournal of Taibah University for Science, 2019
We completely characterize up to an isomorphism those rings whose elements satisfy the equations $ x^4=x $ or $ x^4=-x $ . Specifically, it is proved that a ring is weakly quadratent if, and only if, it is isomorphic to either K, $ \mathbb {Z}_3 ...

Universal Enveloping Commutative Rota–Baxter Algebras of Pre- and Post-Commutative Algebras

open access: yesAxioms, 2017
Universal enveloping commutative Rota–Baxter algebras of pre- and post-commutative algebras are constructed. The pair of varieties (RBλCom, postCom) is proved to be a Poincaré–Birkhoff–Witt-pair (PBW)-pair and the pair (RBCom, preCom) is proven not to be.

Unification Theories: Rings, Boolean Algebras and Yang–Baxter Systems

open access: yesAxioms, 2023
This paper continues a series of papers on unification constructions. After a short discussion on the Euler’s relation, we introduce a matrix version of the Euler’s relation, E I π+U=O.

Technical elements on the rings in men’s artistic gymnastics—a systematic review [PDF]

open access: yesJournal of Men's Health, 2023
Although rings can move freely in all possible directions, by which they differ from all other apparatuses, physical performance at highest level is essetial in men’s artistic gymnastics to fulfill the exercise’s technical requirements in the interest
