Rings whose clean elements are uniquely strongly clean [PDF]
Georgian Mathematical JournalWe define the class of CUSC rings, which are rings whose clean elements are uniquely strongly clean. These rings are a common generalization of the so-called USC rings, introduced by Chen–Wang–Zhou in J. Pure Appl.

Strongly nil regular clean rings
International Mathematical Forum, 2021 For an associative ring Ɽ with identity. We define an element in Ɽ to be strongly nil regular clean or(strongly ƝⱤ-clean), if it is the sum of a (Von Neumann) regular and a nilpotent (that commute with each other).

On Weakly 2-Invo Clean Rings With Some Properties in Graph Theory
International Journal of Mathematics and Mathematical SciencesThe concept of a weakly two-involution clean ring is presented; it is a generalization of two-involution clean ring, which allows the addition of more elements to a ring, which will be observed in its graph theoretic representation.

Symmetrization in Clean and Nil-Clean Rings [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2020 We introduce and investigate D-clean and D-nil-clean rings as well as some other closely related symmetric versions of cleanness and nil-cleanness. A comprehensive structural characterization is given for these symmetrically clean and symmetrically nil ...

On $ mj $-clean ring and strongly $ mj $-clean ring
Turkish Journal of Mathematics, 2022 Summary: In this paper, we introduce the concepts of \(mj\)-clean and strongly \(mj\)-clean rings which are generalizations of \(j\)-clean ring and strongly \(j\)-clean ring, respectively. Let \(R\) be a ring with a nonzero identity and \(m\geq 2\) a positive integer.

Nantong Daxue xuebao. Ziran kexue ban, 2022 A *-ring R is called a medium *-clean ring if every element in R is the sum or difference of a nilpotent with a projection that commute. Fundamenta properties of such *-rings are obtained.

Strongly 2-Nil Clean Rings with Units of Order Two
European Journal of Pure and Applied Mathematics, 2023 A ring R is considered a strongly 2-nil clean ring, or (strongly 2-NC ring for short), if each element in R can be expressed as the sum of a nilpotent and two idempotents that commute with each other.

Turbulent vortex ring/free surface interaction [PDF]
, 1995 The interaction of turbulent vortex rings that approach a clean water surface under various angles is experimentally investigated. The temporal evolution of the vortex rings with an initial Reynolds number of Re_0 = 7500 is characterized by the laminar ...

Minigap, Parity Effect and Persistent Currents in SNS Nanorings [PDF]
, 2006 We have evaluated a proximity-induced minigap in the density of states (DOS) of SNS junctions and SNS nanorings at an arbitrary concentration of non-magnetic impurities. We have demonstrated that an isotropic energy minigap in the electron spectrum opens
