Eigenvalues and bifurcation for Neumann problems with indefinite weights / M. Calanchi, B. Ruf. - In: ELECTRONIC JOURNAL OF DIFFERENTIAL EQUATIONS. - ISSN 1072-6691. - 2021:Special Issue 1(2021 Dec 14), pp. 255-268.
Abstract:
We consider eigenvalue problems and bifurcation of positive solutions for elliptic equations with indefinite weights and with Neumann boundary conditions. We give complete results concerning the existence and non- existence of positive solutions for the superlinear coercive and non-coercive problems, showing a surprising complementarity of the respective results.
