Left Annihilators of Commutators with Derivation on Right Ideals
Communications in Algebra, 2003Abstract Let R be a prime ring of characteristic different from 2, d a non-zero derivation of R, I a non-zero right ideal of R, a ∈ R, S 4(x 1,…, x 4) the standard polynomial in 4 variables. Suppose that, for any x, y ∈ I, a[d([x, y]), [x, y]] = 0. If S 4(I, I, I, I)I ≠ 0, then aI = ad(I) = 0.

Left annihilators of power values of commutators with generalized derivations
Georgian Mathematical Journal, 2012Summary: Let \(R\) be a prime ring with its Utumi ring of quotients \(U\), \(C=Z(U)\) the extended centroid of \(R\), \(H\) a generalized derivation of \(R\) and \(L\) a noncentral Lie ideal of \(R\). Suppose that there exists \(0\neq a\in R\) such that \(a[H(u),u]^n=0\) for all \(u\in L\), where \(n\geq 1\) is a fixed integer.

Skew left braces with non-trivial annihilator
Journal of Algebra and Its Applications, 2019We describe the class of all skew left braces with non-trivial annihilator through ideal extension of a skew left brace. The ideal extension of skew left braces is a generalization to the non-abelian case of the extension of left braces provided by Bachiller in [D. Bachiller, Extensions, matched products, and simple braces, J. Pure Appl.

Left annihilator of generalized derivations on Lie ideals in prime rings
Rendiconti del Circolo Matematico di Palermo (1952 -), 2014For an associative ring \(R\), if \(d\in\text{der}(R)\) and \(F\colon R\to R\) is additive, so that for all \(x,y \in R\) \(F(xy)=F(x)y+xd(y)\) then \((F,d)\) is called a generalized derivation of \(R\). The authors assume that \(R\) is a prime ring, \(a\in R\), \(L\) is a noncentral Lie ideal of \(R\), and \((F,d)\) is a generalized derivation of \(R\)

Left-Right Asymmetry in Pair Annihilation for Transversally Polarized Positrons
Physical Review, 1962S>A left-right asymmetry of the photons in the electronpositron annihilation cross section is found for the case when only the incident positron is polarized. This asymmetry results from a radiative correction. ln the calculation the target electron is unpolarized and it is assumed that the polarizations of the resulting photons are not measured.

Let R be a prime ring of characteristic different from 2 with Utumi quotient ring U and extended centroid C, F a nonzero generalized derivation of R, I an ideal of R, and f(x1,…, xn) a multilinear polynomial over C which is not central valued on R. If 0 ≠ a ∈ R such that for all u, v ∈ f(I), where f(I) is the set of all evaluations of f(x1,…, xn) in I,

Journal of Applied Non-Classical Logics, 2001
This paper is the continuation of [11] where the rotation construction of left-continuous triangular norms was presented. Here the class of triangular subnorms and a second construction, called rotation-annihilation, are introduced: Let T1 be a left-continuous triangular norm.

Let \(R\) be a (semi)prime ring with center \(Z(R)\), \(\lambda\) be a nonzero left ideal of \(R\) and \(F\) a map (not necessarily additive) defined on \(R\). It is a multiplicative generalized derivation if there exists a derivation \(d\) of \(R\) such that \(F(xy) = F(x)y+xd(y)\) for all \(x, y \in R\). Notice that if \(F\) is an additive map of \(R\

Physics of Atomic Nuclei, 2004
We consider the inclusive and associated production of J/ψ mesons under BELLE conditions. In the framework of QCD perturbation theory and nonrelativistic bound-state formalism, the different production mechanisms are analyzed in detail. The calculations are compared with recent experimental data, and significant disagreement is found in a few cases ...
