Boundary value problems for fractional differential equations with three-point fractional integral boundary conditions

Advances in Differential Equations, 2012
This article studies a boundary value problem of nonlinear fractional differential equations with three-point fractional integral boundary conditions. Some new existence results are obtained by applying standard fixed point theorems.

Monotone and convex positive solutions for fourth-order multi-point boundary value problems

Boundary Value Problems, 2011
The existence results of multiple monotone and convex positive solutions for some fourth-order multi-point boundary value problems are established. The nonlinearities in the problems studied depend on all order derivatives. The analysis relies on a fixed

Periodic Impact Motions at Resonance of a Particle Bouncing on Spheres and Cylinders

Advanced Nonlinear Studies, 2017
We investigate the existence of periodic trajectories of a particle, subject to a central force, which can hit a sphere or a cylinder. We will also provide a Landesman–Lazer-type condition in the case of a nonlinearity satisfying a double resonance ...

A study of the coupled fixed point problem for operators satisfying a max-symmetric condition in b-metric spaces with applications to a boundary value problem

, 2016
In this paper, we will consider the coupled fixed point problem for single-valued operators satisfying a symmetric contraction condition with respect to maximum. An application to a periodic boundary value problem illustrates the results.

A generalization of Geraghty's theorem in partially ordered metric spaces and applications to ordinary differential equations

, 2012
The purpose of this article is to present some fixed point theorems for generalized contraction in partially ordered complete metric spaces. As an application, we give an existence and uniqueness for the solution of an initial-boundary-value problem.2000
