Eigenvalues of the p-Laplacian and disconjugacy criteria
Pablo L. De Nápoli, Juan Pablo Pinasco · Journal of Inequalities and Applications · 2006
We derive oscillation and nonoscillation criteria for the one-dimensional -Laplacian in terms of an eigenvalue inequality for a mixed problem. We generalize the results obtained in the linear case by Nehari and Willett, and the proof is based on a Picone-type identity.
