摘要

Let \(\mathfrak {E}\) E be a unital \(*\) -algebra and \(\eta \ne -1\) η - 1 be a nonzero scalar. This paper establishes that if a nonlinear mapping \(\zeta : \mathfrak {E} \rightarrow \mathfrak {E}\) ζ : E E satisfies \( \zeta (\mathcal {U} \bullet \mathcal {V} \circ _\eta \mathcal {W})=\zeta (\mathcal {U}) \bullet \mathcal {V} \circ _\eta \mathcal {W}+\mathcal {U} \bullet \zeta (\mathcal {V}) \circ _\eta \mathcal {W}+\mathcal {U} \bullet \mathcal {V} \circ _\eta \zeta (\mathcal {W})\) ζ ( U V η W ) = ζ ( U ) V η W + U ζ ( V ) η W + U V η ζ ( W ) for all \( \mathcal {U}, \mathcal {V}, \mathcal {W} \in \mathfrak {E}\) U , V , W E , then \(\zeta \) ζ is an additive \(*\) -derivation and fulfils \(\zeta (\eta \mathcal {U})=\eta \zeta (\mathcal {U})\) ζ ( η U ) = η ζ ( U ) for all \(\mathcal {U} \in \mathfrak {E}.\) U E . Additionally, we extend this result to various other algebras.
