Characterizations of Jordan derivations and Jordan homomorphisms

Linear and Multilinear Algebra, 2011
Let 𝒜 be a unital Banach algebra and ℳ be a unital 𝒜-bimodule. We show that if δ is a linear mapping from 𝒜 into ℳ satisfying δ(ST) = δ(S)T +Sδ(T) for any S, T ∈ 𝒜 with ST = W, where W is a left or right separating point of ℳ, then δ is a Jordan derivation.

Jordan, Jordan Right and Jordan Left Derivations on Convolution Algebras

Bulletin of the Iranian Mathematical Society, 2018
A Jordan derivation on a ring $R$ is an additive mapping $d$ that satisfies \[ d(x^2) = d(x) x + x d(x) \] for all $x \in R$; $d$ is said to be a Jordan left derivation if \[ d(x^2) = 2xd(x) \] for all $x \in R$. Jordan right derivations are defined similarly.

On the Stability of Jordan *-Derivation Pairs

Results in Mathematics, 2013
Let \(A\) be a \(*\)-ring and \(X\) be an \(A\)-bimodule. If \(L, R:A \to X\) are additive mappings such that \(L(a^3)=L(a)\cdot (a^*)^2+a\cdot R(a)\cdot a^*+a^2L(a)\) and \(R(a^3)=R(a) \cdot(a^*)^2+a\cdot L(a)\cdot a^*+a^2R(a)\) for all \(a\in A\), then \((L,R)\) is called a Jordan \(*\)-derivation pair. In this paper, the authors prove the Hyers-Ulam
