Abstract

We consider a number of boundary value problems involving the p-Laplacian. The model case is -Δpu=V|u|p-2u for uW01,p(D) with D a bounded domain in ℝn. We derive necessary conditions for the existence of nontrivial solutions. These conditions usually involve a lower bound for a product of powers of the norm of V, the measure of D, and a sharp Sobolev constant. In most cases, these inequalities are best possible. Applications to non-linear eigenvalue problems are also discussed.
