Abstract
This paper is devoted to the study of the effects of indefinite weights on some following nonlinear Neumann problems. Our results establish a relation between the position of a parameter and the number of nontrivial classical solutions of these problems. The proof combines spectral analysis tools, variational methods and the Clark multiplicity theorem.File in questo prodotto:
