Summary: In this paper we study the eigenvalue problem $$ -\Delta_{p}u-a(x)|u|^{p-2}u=\lambda |u|^{p-2}u, \quad u\in W^{1,p}_{0}(\Omega), $$ where $1 less than p\le N, $Omega$ is a bounded domain containing 0 in $mathbbR^N, Delta_p$ is the p-Laplacean, and $a(x)$ is a function related to Hardy-Sobolev inequality. The weight function $V(x)inL^s(Omega)$ may change sign and has nontrivial positive part. We study the simplicity, isolatedness of the first eigenvalue, nodal domain properties. Furthermore we show the existence of a nontrivial curve in the Fucik spectrum.$
