The second order elliptic differential equations [GRAPHICS] and L(2)(y;x) = Delta y + p(x)\y\(gamma)signy = 0, 1 not equal gamma > 0 are considered in an exterior domain Omega subset of R(n), n greater than or equal to 2, where p can change sign. Some new sufficient conditions for the oscillation of solutions of (1.1) and (1.2) are established.
