 Jordan $(\varphi,\psi)$-derivations in $JB^*$-triples Commun. Korean Math. Soc. 2011 Vol. 26, No. 4, 585-589 https://doi.org/10.4134/CKMS.2011.26.4.585Published online December 1, 2011 Mohammad Sal Moslehian and Abbas Najati Ferdowsi University of Mashhad, University of Mohaghegh Ardabili Abstract : Using algebraic methods, we prove that every Jordan $(\varphi,\psi)$-derivation is a $(\varphi,\psi)$-derivation under certain conditions. In particular, we conclude that every Jordan $\theta$-derivation is a $\theta$-derivation.
