Bifurcation beyond the principal eigenvalues for Neumann problems with indefinite weights / M. Calanchi, B. Ruf. - In: ADVANCES IN PURE AND APPLIED MATHEMATICS. - ISSN 1869-6090. - 14:2(2023), pp. 14-30. [10.21494/ISTE.OP.2023.0935]
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.
