Stability of ternary Jordan homomorphisms and derivations associated to the generalized Jensen equation
M. Eshaghi Gordji, E. Rashidi, J. M. Rassias
In this paper, we establish the generalized Hyers-Ulam stability of Jordan homomorphisms and Jordan derivations between ternary algebras via the generalized Jensen equation $rf(\fr…
