On the second eigenvalue of nonlinear eigenvalue problems. <i>Electronic Journal of Differential Equations, 2018</i>(199), pp. 1-22.1072-6691https://hdl.handle.net/10877/15495This article is devoted to the characterization of the second eigenvalue of nonlinear eigenvalue problems. We propose an abstract approach which allows to treat nonsmooth quasilinear problems and also to recover, in a unified way, previous results concerning the p-Laplacian.Text22 pages1 file (.pdf)enAttribution 4.0 InternationalNonlinear eigenvalue problemsVariational methodsQuasilinear elliptic equationsArticle
