On a Nonlinear Elliptic Eigenvalue Problem

Journal of Differential Equations, 1995
The eigenvalue problem \(- \Delta u- \mu u= \lambda g(x, u)\) in \(D\), \(u= 0\) on \(\partial D\), with prescribed energy condition is considered. Multiplicity results are proved, based on Lyusternik-Schnirelman theory.

Eigenvalue Problems for Systems of Nonlinear Boundary Value Problems on Time Scales

Advances in Difference Equations, 2007
Values of λ are determined for which there exist positive solutions of the system of dynamic equations, , , for , satisfying the boundary conditions, , where is a time scale. A Guo-Krasnosel'skii fixed point-theorem is applied.

Existence of solutions to a third-order multi-point problem on time scales

Electronic Journal of Differential Equations, 2007
We are concerned with the existence and form of solutions to nonlinear third-order three-point and multi-point boundary-value problems on general time scales.
