Existence Theorem for a Fractal Sturm-Liouville Problem [PDF]

In this article, using a new calculus defined on fractal subsets of the set of real numbers, a Sturm-Lioville type problem is discussed, namely the fractal Sturm-Liouville problem.

Generalizing Liouville-type Problems for Differential 1-Forms from Lq Spaces to Non-Lq Spaces

, 2016
We obtain Liouville-type results for closed and p-pseudo-coclosed differential 1-forms ! with energy of lim inf r!1 1 r2 R B(x0;r) j!jqdv \u3c 1 (that is, 2-finite growth), which extends finite q-energy ( R M j!jqdv \u3c 1) in Lq spaces to infinite q ...

A NONLINEAR LIOUVILLE THEOREM FOR FRACTIONAL EQUATIONS IN THE HEISENBERG GROUP

, 2020
. We establish a Liouville-type theorem for a subcritical nonlinear problem, involving a fractional power of the subLaplacian in the Heisenberg group. To prove our result we will use the local realization of fractional CR covariant operators, which can ...

Second-order n -point eigenvalue problems on time scales

Advances 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

Electronic 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.

Precise asymptotic spreading behavior for an epidemic model with nonlocal dispersal

This paper is to derive the precise asymptotic spreading behavior for an epidemic model with nonlocal dispersal. The proof is based on a Liouville type theorem on the positive bounded entire solutions.
