Minimax Theory and its Applications 02 (2017), No. 2, 249--263 Copyright Heldermann Verlag 2017 Multiplicity Results for a Non-Homogeneous Neumann Problem via a Variational Principle of Ricceri Saeid Shokooh Dept. of Mathematics, Faculty of Sciences, Gonbad Kavous University, Gonbad Kavous, Iran shokooh@gonbad.ac.ir In this paper, the existence and multiplicity of weak solutions are obtained for a class of non-homogeneous Neumann problems. The proof of the main results relies on a recent variational principle due to Ricceri. Keywords: Multiplicity results, non-homogeneous differential operator, Orlicz-Sobolev space.
