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

Aequationes mathematicae, 2012
Let R be a 2-torsion free semiprime *-ring, σ, τ 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 (σ, τ)*-derivation if and only if d is a Jordan triple (σ, τ)*-derivation. (ii) f is a generalized Jordan (σ, τ)*-derivation if and only if f is a generalized Jordan triple (σ, τ)*

JORDAN *-DERIVATIONS AND QUADRATIC JORDAN *-DERIVATIONS ON REAL C*-ALGEBRAS AND REAL JC*-ALGEBRAS

International Journal of Geometric Methods in Modern Physics, 2013
In this work, we introduce quadratic Jordan *-derivations on real C*-algebras and real JC*-algebras and prove the Hyers–Ulam stability of Jordan *-derivations and of quadratic Jordan *-derivations on real C*-algebras and real JC*-algebras. We also establish the superstability of such derivations on real C*-algebras and real JC*-algebras by using a ...

On Jordan left derivations

2016
Let \(R\) be a ring and \(X\) be a left \(R\)-module such that \(aRx = 0\), where \(a \in R\) and \(x \in X\), implies \(a = 0\) or \(x = 0\). Suppose there exists a nonzero additive map \(D : R \to X\) satisfying \(D(a^ 2) = 2aD(a)\) for every \(a \in R\) (such maps are called Jordan left derivations). \textit{J. Vukman} and the reviewer [Proc.

On the norm of Jordan \(*\)-derivations

2020
In this paper, the authors are interested in the norm of the inner Jordan *-derivation acting on the Banach algebra of all bounded linear operators. Using the maximal numerical range, the authors give some lower bounds.

Jordan derivable mappings on $$B(H)$$

Acta Mathematica Hungarica
Let \(H\) be a Hilbert space. In this paper, sufficient conditions are given for the existence of Jordan derivations and Jordan generalized derivations over \(B(H)\). The following is the main result. \par Theorem. Let \(H\) be a real or complex Hilbert space with \(\operatorname{dim}(H)\ge 2\) and \(\Omega\in B(H)\) be given.

Jordan left derivations on semiprime rings

2016
If \(R\) is a ring then \(D\in\text{End}(R,+)\) is a Jordan left derivation of \(R\) when \(D(x^2)=2xD(x)\) for all \(x\in R\). The author proves two results for such maps analogous to results known for derivations. These are: if \(R\) is a 2-torsion free semiprime ring, \(D\) a Jordan left derivation of \(R\), and \(n>1\) so that \(D(x)^n=0\) for all \
