Two remarks on Lie rings of $2\times 2$ matrices over commutative associative rings

open access: yes, 2020
summary:Let $C$ be an associative commutative ring with 1. If $a\in C$, then $aC$ denotes the principal ideal generated by $a$. Let $l, m, n$ be nonzero elements of $C$ such that $mn \in lC$. The set of matrices $\left( \begin{smallmatrix} a_{11} & a_{12}

SMARANDACHE LOOPS [PDF]

open access: yes, 2002
The theory of loops (groups without associativity), though researched by several mathematicians has not found a sound expression, for books, be it research level or otherwise, solely dealing with the properties of loops are absent.

Therapeutic Apheresis for Intravenous Methylprednisolone‐Refractory Neuromyelitis Optica Spectrum Disorder: Clinical and Radiological Outcomes in a Single‐Center Case Series

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

On the mapping xy→(xy)n in an associative ring

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We consider the following condition (*) on an associative ring R:(*). There exists a function f from R into R such that f is a group homomorphism of (R,+), f is injective on R2, and f(xy)=(xy)n(x,y) for some positive integer n(x,y)>1. Commutativity and

Hilbert's basis theorem and simplicity for non-associative skew Laurent polynomial rings and related rings

open access: yes, 2023
We introduce non-associative skew Laurent polynomial rings over unital, non-associative rings. We prove simplicity results and a Hilbert's basis theorem for these.

HYPERCOMMUTING VALUES IN ASSOCIATIVE RINGS WITH UNITY [PDF]

open access: yesJournal of the Australian Mathematical Society, 2013
AbstractLet $K$ be a commutative ring with unity, $R$ an associative $K$-algebra of characteristic different from $2$ with unity element and no nonzero nil right ideal, and $f({x}_{1} , \ldots , {x}_{n} )$ a multilinear polynomial over $K$. Assume that, for all $x\in R$ and for all ${r}_{1} , \ldots , {r}_{n} \in R$ there exist integers $m= m(x, {r}_{1}

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

On the associated graded ring of a group ring

open access: yesJournal of Algebra, 1968
In this paper we show that if the group ring KG of a group G over a field K is filtered by the powers of its augmentation ideal, then the associated graded ring is isomorphic to the universal enveloping algebra of the p-Lie algebra gr? G oz K, where gr?

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.
