If the energy spectrum of an extremal invariant state w is not the whole real line, it is shown that co is either pure or uniquely decomposed into nmtually disjoint pure states in the way that co = X-~fXo~oatdt where 4~ is a pure state satisfying q~oax = 4~ with X > 0. Next we give a slightly genera

Let ( , , J 1 ) and ( , , J 2 ) denote two Hermitian structures on a 2n-dimensional Euclidean space (V , , ). If n is even and J 1 ,J 2 have opposite orientations, then there exist non-zero vectors v, w β V such that J 1 (v) = J 2 (v) and J 1 (w) = -J 2 (w). If n is odd and J 1 , J 2 have the same o
