Generalized Rickart ∗ \ast -Rings

Siberian Mathematical Journal, 2021
A ring \(R\) with an involution \(*\) is a generalized Rickart \(*\)-ring if for every \(x\in R\) there is a positive integer \(n\) such that the right annihilator of \(x^n\) is generated by a projection. The authors study various properties of generalized Rickart \(*\)-rings and their relations with generalized Baer \(*\)-rings and other related rings

Young's modulus and Poisson's ratio for TiO2-based nanotubes and nanowires: modelling of temperature dependence [PDF]

RSC Advances, 2016
In this work molecular mechanics simulations with the help of interatomic potentials were employed to predict the temperature dependence of the Young's modulus and Poisson's ratio of a number of TiO2-based four-facetted nanotubes and nanowires.

$\ast$-Semiclean rings

Turkish Journal of Mathematics, 2023
A ring $R$ is called semiclean if every element of $R$ can be expressed as sum of a periodic element and a unit. In this paper, we introduce a new class of ring, which is the $\ast$-version of the semiclean ring, i.e. the $\ast$-semiclean ring. A $\ast$-ring is $\ast$-semiclean if each element is a sum of a $\ast$-periodic element and a unit. The term $

Local Definitizability of $${{T^{[\ast]}T}}$$ and $${{TT^{{[\ast]}}}}$$ [PDF]

Integral Equations and Operator Theory, 2011
The first section of the article presents a simple proof of the coincidence of non-zero spectra of products \(AB\) and \(BA\) of two linear closed and densely defined operators \(A\) and \(B\) acting between Banach spaces, provided that the resolvent sets of \(AB\) and \(BA\) are non-empty; this assertion was obtained earlier by \textit{V.
