Second-order n -point eigenvalue problems on time scales

open access: yesAdvances in Difference Equations, 2006
We discuss conditions for the existence of at least one positive solution to a nonlinear second-order Sturm-Liouville-type multipoint eigenvalue problem on time scales.

A generalization of Gordon's theorem and applications to quasiperiodic Schrodinger operators

open access: yesElectronic Journal of Differential Equations, 2000
We present a criterion for absence of eigenvalues for one-dimensional Schrodinger operators. This criterion can be regarded as an L^1-version of Gordon's theorem and it has a broader range of application.

A Liouville theorem for the Degasperis-Procesi equation

open access: yes, 2016
Doi 10.2422/2036-2145.201410_014International audienceWe prove that the only global, strong, spatially periodic solution to the Degasperis-Procesi equation, vanishing at some point (t0, x0), is the identically zero solution.
