A note on the singular Sturm-Liouville problem with infinitely many solutions

Electronic Journal of Differential Equations, 2002
We consider the Sturm-Liouville nonlinear boundary-value problem $$ displaylines{ -u''(t) = a(t)f(u(t)), quad 0 < t < 1, cr alpha u(0) - eta u'(0) =0, quad gamma u(1) + delta u'(1) = 0, } $$ where $alpha$, $eta$, $gamma$, $delta geq 0$, $alpha gamma ...

On the Nonhomogeneous Fourth-Order p-Laplacian Generalized Sturm-Liouville Nonlocal Boundary Value Problems

Discrete Dynamics in Nature and Society, 2012
We study the nonlinear nonhomogeneous n-point generalized Sturm-Liouville fourth-order p-Laplacian boundary value problem by using Leray-Schauder nonlinear alternative and Leggett-Williams fixed-point theorem.

Liouville theorems for III-posed problems

Journal of Mathematical Analysis and Applications, 1984
The paper claims to correct an error in a paper of \textit{H. Brézis} and \textit{J. A. Goldstein} [Improp. posed Bound. Value Probl., Conf. Albuquerque 1974, 65-75 (1975; Zbl 0318.35072)], noting that this error was not picked up by the introduction given by Mathematical Reviews (M.R. 57 {\#}16883) or the review in Zentralblatt für Mathematik.

Existence and uniqueness of solutions for mixed fractional q-difference boundary value problems

Boundary Value Problems, 2019
In this paper, we investigate the existence and uniqueness of solutions for mixed fractional q-difference boundary value problems involving the Riemann–Liouville and the Caputo fractional derivative. By using the Guo–Krasnoselskii fixed point theorem and

On the Gibbs-Liouville theorem in classical mechanics

, 2019
In this article, it is argued that the Gibbs-Liouville theorem is a mathematical representation of the statement that closed classical systems evolve deterministically.

A study for a higher order Riemann-Liouville fractional differential equation with weakly singularity

Electronic Research Archive
In this paper, we study an initial value problem with a weakly singular nonlinear fractional differential equation of higher order. First, we establish the existence of global solutions to the problem within the appropriate function space.

Uncertain fractional forward difference equations for Riemann–Liouville type

Advances in Difference Equations, 2019
To model complex systems with discrete-time features and memory effects in the uncertain environment, a definition of an uncertain fractional forward difference equation with Riemann–Liouville-like forward difference is introduced.
