On Hochstadt-Lieberman Theorem For Sturm-Liouville Operators

open access: yes, 2011
The inverse spectral problem of the Sturm-Liouville operator Lq = -d2/dx2 +q(x) is considered, where q(x) is an integrable function on (0,1).

A Note on Fractional Equations of Volterra Type with Nonlocal Boundary Condition

open access: yesAbstract and Applied Analysis, 2013
We deal with nonlocal boundary value problems of fractional equations of Volterra type involving Riemann-Liouville derivative. Firstly, by defining a weighted norm and using the Banach fixed point theorem, we show the existence and uniqueness of ...

A C1 Arnol'd-Liouville theorem

open access: yes, 2020
International audienceIn this paper, we prove a version of Arnol'd-Liouville theorem for C 1 commuting Hamiltonians. We show that the Lipschitz regularity of the foliation by invariant Lagrangian tori is crucial to determine the Dynamics on each ...

On a Liouville type theorem for isotropic homogeneous fully nonlinear elliptic equations in dimension two [PDF]

open access: yes, 2002
In this paper we establish a Liouville type theorem for fully nonlinear elliptic equations related to a conjecture of De Giorgi in R². We prove that if the level lines of a solution have bounded curvature, then these level lines are straight lines.

A Survey of Nonlinear Sturm-Liouville Equations

open access: yes, 2013
[[abstract]]This note gives a brief survey of existence, uniqueness and bifurcation results for nonlinear Sturm-Liouville equations. Early in 1960, Nehari made an interesting proposal to study solutions with a prescribed number of nodes.

The sharp exponent for a Liouville-type theorem for an elliptic inequality

open access: yes, 2002
We determine the sharp exponent for a Liouville-type theorem for an elliptic inequality. This answers a question raised in [1] which is related to a conjecture by De Giorgi [5]

Disproof of Bell's Theorem [PDF]

open access: yes, 2011
We illustrate an explicit counterexample to Bell's theorem by constructing a pair of dichotomic variables that exactly reproduce the EPR-Bohm correlations in a manifestly local-realistic ...

Existence of solutions for a system of mixed fractional differential equations

open access: yesJournal of Taibah University for Science, 2018
The aim of this work is to investigate, by the help of Krasnoselskii's fixed point theorem, the existence of solutions for a system of fractional differential equations involving left and right Riemann–Liouville fractional derivatives.
