The radical cations of dicyclopropylidenemethane (2) and its octamethyl derivative (2-Me8) are prone to rearrangements into those of (2-methylallylidene)cyclopropane (2a) and its octamethyl derivative (2a-Me8), respectively, by opening one three-membered ring. In contrast to the radical cations of bicyclopropylidene (1) and its octamethyl derivative (1-Me8), 2*+ and 2-Me8*+ are stable to openin...
Abstract: A ring R is called a refinement ring if the monoid of finitely generated projective R- modules is refinement. Let R be a commutative refinement ring and M, N, be two finitely generated projective R-nodules, then M~N if and only if Mm ~Nm for all maximal ideal m of R. A rectangular matrix A over R admits diagonal reduction if there exit invertible matrices p and Q such that PAQ is...
This article examines annihilators in the skew polynomial ring $R[x;alpha,delta]$. A ring is strongly right $AB$ if everynon-zero right annihilator is bounded. In this paper, we introduce and investigate a particular class of McCoy rings which satisfy Property ($A$) and the conditions asked by P.P. Nielsen. We assume that $R$ is an ($alpha$,$delta$)-compatible ring, and prove that, if $R$ is ni...
In this article our attempt is to study the ring theoretic properties of $t^2$-symmetric and strongly rings tripotent elements a ring. Let $R$ be $t$ element $R$, then said if $abc=0$ implies $acbt^2=0$ for all $a,b,c\in R$. It has been proved that only $t^2$ left semicentral $t^2Rt^2$ symmetric We also introduce establish various it.
let $r$ be a ring with unity. the undirected nilpotent graph of $r$, denoted by $gamma_n(r)$, is a graph with vertex set ~$z_n(r)^* = {0neq x in r | xy in n(r) for some y in r^*}$, and two distinct vertices $x$ and $y$ are adjacent if and only if $xy in n(r)$, or equivalently, $yx in n(r)$, where $n(r)$ denoted the nilpotent elements of $r$. recently, it has been proved that if $r$ is a left ar...
دل استاندارد ذرات بنیادی به عنوان مدلی برای توصیف برهم کنش بین ذرات بنیادی، برخلاف موفقیت های فراوان مدل کاملی برای ذرات بنیادی نیست. بنابراین فیزیک پیشگان به دنبال مدلی فراسوی مدل استاندارد هستند که یکی از این مدل ها، نظریه میدان در فضای ناجابجایی است. برای نوشتن مدل استاندارد در فضای ناجابجایی دو رهیافت پیشنهاد شده است. در رهیافت اول گروه تقارنی را $u_{star}(3) imes u_{star}(2) imes u_{star...
