Global multiplicity for parametric anisotropic Neumann $(p,q)$-equations

Abstract

We consider a Neumann boundary value problem driven by the anisotropic (p,q)(p,q)-Laplacian plus a parametric potential term. The reaction is ``superlinear". We prove a global (with respect to the parameter) multiplicity result for positive solutions. Also, we show the existence of a minimal positive solution and finally, we produce a nodal solution.
