  • Let 𝒦 be a ring. An additive map 𝖚 → 𝖚 is called Jordan involution on 𝒦 if (𝖚) = 𝖚 and (𝖚𝖛+𝖛𝖚) = 𝖚𝖛+𝖛𝖚 for all 𝖚, 𝖛 ∈ 𝒦. If Θ is a (non-zero) 𝜂-generalized derivation on 𝒦 associated with a derivation Ω on 𝒦, then it is shown that Θ(𝖚) = 𝛄𝖚 for all u ∈ 𝒦 such that 𝛄 ∈ Ξ and 𝛄2 = 1, whenever Θ possesses [Θ(𝖚), Θ(𝖚)] = [𝖚, 𝖚] for all 𝖚 ∈ 𝒦.
