Three weak solutions for a class of Neumann boundary value systems involving the (p1,...,pn)-Laplacian

Abstract

In this paper, we establish the existence of two intervals of positive real parameters $\\lambda$ for which a class of Neumann boundary value equations involving the (p1,...,pn)-Laplacian admits three weak solutions, whose norms are uniformly bounded with respect to $\\lambda$ belonging to one of the two intervals. The approach is based on variational methods.
