A general Liouville-type theorem for the 3D steady-state Magnetic-Bénard system

open access: yes
We establish a Liouville-type theorem for the elliptic and incompressible Magnetic-Bénard system defined over the entire three-dimensional space. Specifically, we demonstrate the uniqueness of trivial solutions under the condition that they belong to ...

Positive solutions for fractional differential equations with variable coefficients

open access: yesElectronic Journal of Differential Equations, 2012
In this article, we study the existence of the positive solutions for a class of differential equations of fractional order with variable coefficients.

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 Theorem of Rolewicz's Type for Measurable Evolution Families in Banach Spaces

open access: yes, 2001
Let $varphi$ be a positive and non-decreasing function defined on the real half-line and ${mathcal U}$ be a strongly measurable, exponentially bounded evolution family of bounded linear operators acting on a Banach space and satisfing a certain ...

Kochen-Specker theorem for von Neumann algebras

open access: yes, 2005
The Kochen-Specker theorem has been discussed intensely ever since its original proof in 1967. It is one of the central no-go theorems of quantum theory, showing the non-existence of a certain kind of hidden states models. In this paper, we first offer a
