Let $\lambda _1^+>0$ be the principal eigenvalue of -pu=g(x)|u|p-2u    in ,        g(x)|u|p>0, (2) with $u_1^+>0$ the associated eigenfunction. We prove that, if $\int _{\mathbb {R}^N}f|u_1^+|^{p^*}<0$, $\int _{\mathbb {R}^N}h|u_1^+|^q>0$ if $1<q<p$ and $\int _{\mathbb {R}^N}h|u_1^+|^q<0$ if $p<q<p^*$, then there exist $\lambda ^*>\lambda _1^+$ and $\alpha ^*>0$, such that for $\lambda \in [\lambda _1^+, \lambda ^*)$ and $\alpha \in [0, \alpha ^*)$, (1) has at least one positive solution.
