A characterization of Jordan left ∗-centralizers in rings with involution [PDF]

Applied Mathematics & Information Sciences, 2017
Let R be a ring with involution ∗. An additive mapping T : R → R is called a left ∗-centralizer (resp. Jordan left ∗-centralizer) if T(xy) = T(x)y∗ (resp. T(x2) = T(x)x∗) holds for all x,y ∈ R, and a reverse left ∗-centralizer if T(xy) = T(y)x∗ holds for

On Jordan left-I-centralizers of prime and semiprime gamma rings with involution

Journal of the Egyptian Mathematical Society, 2016
Let M be a 2-torsion free Γ-ring with involution I satisfying the condition xαyβz=xβyαz for all x,y,z∈M and α,β∈Γ. The object of our paper is to show that every Jordan left-I-centralizer on a semiprime Γ-ring with involution I, is a reverse left-I ...

Equivalent characterization of right (left) centralizers or centralizers on Banach algebras

2023
Summary: Let \(\mathcal{A}\) be a unital Banach algebra, \(w\in\mathcal{A}\), and \(\gamma : \mathcal{A} \to \mathcal{A}\) is a continuous linear map. We show that \(\gamma\) satisfies \(a\gamma(b)=\gamma(w)\) (\(\gamma(a)b=\gamma(w)\)) whenever \(a,b\in \mathcal{A}\) with \(ab=w\) and \(w\) is a left (right) separating point in \(\mathcal{A}\) if and ...

Central and left division hepatectomies in two dogs

Journal of the American Veterinary Medical Association, 2023
Abstract OBJECTIVE To describe the management of extensive hepatectomy in 2 dogs. ANIMALS A 10-year-old female intact mixed-breed dog (case 1) and an 11-year-old male castrated mixed-breed dog (case 2) were presented for surgical evaluation following diagnosis of a hepatic mass.

Characterizing left centralizers by their action on a polynomial

Publicationes Mathematicae Debrecen, 2004
For a (not necessarily unital) ring \(R\), an additive map \(\varphi\colon R\to R\) is called a left centralizer, if \(\varphi(xy)=\varphi(x)y\) for all \(x,y\in R\). The paper under review studies a more general condition, when the multiplication is replaced by an arbitrary multilinear polynomial in noncommuting variables.

On Jordan Triple α-*Centralizers Of Semiprime Rings

Demonstratio Mathematica, 2014
Let R be a 2-torsion free semiprime ring equipped with an involution *. An additive mapping T : R→R is called a left (resp. right) Jordan α-*centralizer associated with a function α: R→R if T(x2)=T(x)α(x*) (resp. T(x2)=α(x*)T(x)) holds for all x ∊ R.
