On a variational approach to existence and multiplicity results for semipositone problems
Electronic journal of differential equations, Tome 2006 (2006)
In this paper we present a novel variational approach to the question of existence and multiplicity of positive solutions to semipositone problems in a bounded smooth domain of $\mathbb{R}^N$. We consider both the sublinear and superlinear cases.
