Abstract. In this paper, we investigate a class of problems with Neumann boundary data in Musielak--Orlicz--Sobolev spaces $W^1L_M(\Omega )$. We prove the existence of infinitely many weak solutions under some hypotheses. We also provide some particular cases and a concrete example in order to illustrate the main results. Our results are an improvement and generalization of the relative results [1].
