Approximate homomorphisms and derivations between C*-ternary algebras.

In 1940, Ulam proposed the famous Ulam stability problem. In this paper we introduce a general Cauchy–Jensen functional equation and prove the generalized Ulam stability of C*-ternary homomorphisms and C*-ternary derivations in C*-ternary algebras for the general Cauchy–Jensen equation.
