Let k, n(1),..., n(k) be positive integers such that n(i) >= 2 for i = 1,..., k and let M-ni denote the algebra of n(i) x n(i) matrices over a field F for i = 1,..., k. Let circle times(i=1)k M-ni be the tensor product of M-n1,..., M-nk. We obtain a structural characterization of additive maps ps...
