Abstract : In this article, it is proved that under some conditions every bijective Jordan triple product homomorphism from generalized matrix algebras onto rings is additive. As a corollary, we obtain that every bijective Jordan triple product homomorphism from $M_n(\Aa)$ ($\Aa$ is not necessarily a prime algebra) onto an arbitrary ring $\mc{R}'$ is additive.
Keywords : Jordan triple product homomorphism, generalized matrix algebra, additive map
