Multiple solutions for Neumann systems in an Orlicz-Sobolev space setting
Ghasem A. Afrouzi; John R. Graef; Saeid Shokooh;Abstract
In this paper, the authors improve some results on the existence of at least three weak solutions for non-homogeneous systems. The proof of the main result relies
on a recent variational principle due to Ricceri.
