WebConsider a point P of M where either K is negative, or K has an isolated zero. Let H1, H2 be the two open half-spaces bounded by the tangent plane of M at P. For any neighbourhood U of P on M, there are points of U lying in H1, and points of Ό lying in H2. The proof of this is, of course, quite elementary if K(P) < 0, and considerably less so if K(P) = 0 ([2], p. 157).
