In this paper we prove the existence of an infinite number of radial solutions of Δu+K(r)f(u)=0 on the exterior of the ball of radius R centered at the origin in RN such that with prescribed number of zeros where f:R→R is odd and there exists a β>0 with f<0 on (0,β), f>0 on e152b9087654428a30e310b9225d" title="Click to view the MathML source">(β,∞) with f superlinear for large u , and K(r)∼r−α with 0<α<N.
