In this paper, by constructing invariant sets of descending flow, we use variationalmethod to study existence of infinitely many nodal solutions for the p-Laplacian equation involving Hardy-Sobolev subcritical singular and non-singular termswhereλandμare two positive parameters andΩ(?)Rn is a bounded domain with smooth boundary (?)Ωand contains 0 in its interior,△pu = div(|▽u|p-2▽u) is the p-Laplacian operator. We assume throughout that : 1 < p < n, 0≤s < p, p≤q< p*(s) = (n-s)/(n-p)p, p≤r * = p*(0) = np/n-p. |
