Anti-commutative anti-associative algebras. Acaa-algebras

Let $(A,\mu)$ be a nonassociative algebra over a field of characteristic zero. The polarization process allows us to associate two other algebras, and this correspondence is one-one, one commutative, the other anti-commutative. Assume that $\mu$ satisfies a quadratic identity $\sum_{\sigma \in \Sigma_3} a_{\sigma}\mu(\mu(x_{\sigma(i)},x_{\sigma(j)}),x_{\sigma(k)}-a_{\sigma}\mu(x_{\sigma(i)},\mu(x_{\sigma(j)},x_{\sigma(k)})=0.$ Under certain conditions, the polarization of such a multiplication determines an anticommutative multiplication also verifying a quadratic identity. Now only two identities are possible, the first is the Jacobi identity which makes this anticommutative multiplication a Lie algebra and the multiplication $\mu$ is Lie admissible, the second, less classical is given by $[[x,y],z]=[[y,z],x]=[[z,x],y].$ Such a multiplication is here called Acaa for Anticommutative and Antiassociative. We establish some properties of this type of algebras.
