Existence of non-negative solutions for semilinear elliptic systems via variational methods
Nonlinear Analysis, 2012 In this paper we consider a semilinear elliptic system with nonlinearities, indefinite weight functions and critical growth terms in bounded domains. The existence result of nontrivial nonnegative solutions is obtained by variational methods.

On the second eigenvalue of a Hardy-Sobolev operator
Electronic Journal of Differential Equations, 2004 In this note, we study the variational characterization and some properties of the second smallest eigenvalue of the Hardy-Sobolev operator $L_{mu}:=-Delta_{p}-frac{mu}{|x|^p}$ with respect to an indefinite weight $V(x)$.

Eigenvalue problems for the p-Laplacian with indefinite weights
Electronic Journal of Differential Equations, 2001 We consider the eigenvalue problem $-Delta_p u=lambda V(x) |u|^{p-2} u, uin W_0^{1,p} (Omega)$ where $p>1$, $Delta_p$ is the p-Laplacian operator, $lambda >0$, $Omega$ is a bounded domain in $mathbb{R}^N$ and $V$ is a given function in $L^s (Omega)$ ($s$
