Based on the relation between the notions of Lie triple systems and Jordan algebras, we introduce the n-ary Jordan algebras, an n-ary generalization of Jordan algebras obtained via the generalization of the following property [R x , R y ] ∈ Der (A) , where A is an n-ary algebra. Next, we study a ternary example of these algebras. Finally, based on the construction of a family of ternary algebras defined by means of the Cayley-Dickson algebras, we present an example of a ternary D x,y -derivation algebra (n-ary D x,y -derivation algebras are the non-commutative version of n-ary Jordan algebras).
