Title: Existence and multiplicity of positive solutions for a singular problem associated to the p-Laplacian operator Authors: Carlos Aranda (Univ. de Tarapaca, Arica, Chile) Tomas Godoy (Univ. Nacional de Cordoba, Argentina) Abstract: Consider the problem $$ -\Delta_{p}u=g(u) +\lambda h(u)\quad\hbox{in }\Omega $$ with $u=0$ on the boundary, where $\lambda\in(0,\infty)$, $\Omega$ is a strictly convex bounded and $C^{2}$ domain in $\mathbb{R}^{N}$ with $N\geq2$, and $1
