Existence of three solutions for parametric p-Laplacian equations in ℝN
Abstract
In this paper we deal with a nonlinear elliptic problem in the whole space ℝN involving the p-Laplacian operator with p>N. Under suitable assumptions on the potential term and on the nonlinearity, we establish the existence of at least three distinct weak solutions. Our approach is variational and relies on two different three critical points theorems. The results extend to higher dimensions some recent multiplicity theorems for one-dimensional p-Laplacian equations on the real line, and provide explicit ranges for the parameter λ> 0 ensuring the existence of multiple solutions, which are nonnegative under additional sign conditions. The nontriviality of the solutions is also discussed. Finally, applications to problems whose nonlinearities have separated variables are presented.
