Arbitrarily small weak solutions for a nonlinear eigenvalue problem in Orlicz-Sobolev spaces

Under an appropriate oscillating behavior of the nonlinear term, the existence of a determined open interval of positive parameters for which an eigenvalue non-homogeneous Neumann problem admits infinitely many weak solutions that strongly converges to zero, in an appropriate Orlicz-Sobolev space, is proved. Our approach is based on variational methods. The abstract result of this paper is illustrated by a concrete case.
