Let J be a finite-dimensional semi-simple Jordan algebra over an algebraically closed field of characteristic 0. In this article, the diagonal action of the automorphism group of J on the n-fold product J × ... × J is studied. In particular, it is shown that the orbit through an n-tuple x = (x1, ..., xn) is closed if and only if the Jordan subalgebra generated by the elements x1, ..., xn is semi-simple.
Classification : 17C20, 17C30
