Characterizations of (Jordan) derivation on Banach algebra with local actions

open access: yes, 2022
Let $\mathcal{A}$ be a unital Banach $*$-algebra and $\mathcal{M}$ be a unital $*$-$\mathcal{A}$-bimodule. If $W$ is a left separating point of $\mathcal{M}$, we show that every $*$-derivable mapping at $W$ is a Jordan derivation, and every $*$-left ...

(σ,τ )– (J,R) – DERIVATIONS ON JORDAN IDEALS

open access: yesمجلة بغداد للعلوم, 2009
Let R be an associative ring with center Z(R). A well known results proved by Bell and kappe concering derivations in prime rings have been extensively studied by many authors, several of these outhers extended these result for a - derivation like ...

On certain functional equation in prime rings

open access: yesOpen Mathematics, 2022
The purpose of this paper is to prove the following result. Let RR be prime ring of characteristic different from two and three, and let F:R→RF:R\to R be an additive mapping satisfying the relation F(x3)=F(x2)x−xF(x)x+xF(x2)F\left({x}^{3})=F\left({x}^{2})

The range of a derivation on a Jordan–Banach algebra [PDF]

open access: yesStudia Mathematica, 2001
I. M. Singer and J. Wermer proved in 1955 that a continuous derivation on a commutative Banach algebra has the range in the (Jacobson) radical of the algebra, and 30 years later M. P. Thomas showed that the continuity assumption is redundant. The noncommutative Singer-Wermer conjecture, whether a (not necessarily continuous) derivation on a Banach ...

Jordan derivations on certain Banach algebras

open access: yes, 2023
In this paper, we study the types of Jordan derivations of a Banach algebra $A$ with a right identity $e$. We show that if $eA$ is commutative and semisimple, then every Jordan derivation of $ A $ is a derivation. In this case, Jordan derivations map $A$

Jordan (α,β)-Derivations on Operator Algebras

open access: yesJournal of Function Spaces, 2017
Let A be a CSL subalgebra of a von Neumann algebra acting on a Hilbert space H. It is shown that any Jordan (α,β)-derivation on A is an (α,β)-derivation, where α,β are any automorphisms on A. Moreover, the nth power (α,β)-maps on A are investigated.

GENERALIZED JORDAN DERIVATIONS ON SEMIPRIME RINGS [PDF]

open access: yesJournal of the Australian Mathematical Society, 2019
The purpose of this note is to prove the following. Suppose $\mathfrak{R}$ is a semiprime unity ring having an idempotent element $e$ ($e\neq 0,~e\neq 1$) which satisfies mild conditions. It is shown that every additive generalized Jordan derivation on $\mathfrak{R}$ is a generalized derivation.

Notes on Jordan (σ, τ)*-derivations and Jordan triple (σ, τ)*-derivations

open access: yes, 2013
Let R be a 2-torsion free semiprime *-ring, sigma, tau two epimorphisms of R and f, d : R -> R two additive mappings. In this paper we prove the following results: (i) d is a Jordan (sigma, tau)*-derivation if and only if d is a Jordan triple (sigma, tau)
