On Solutions of the Nonlocal Generalized Coupled Langevin‐Type Pantograph Systems

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
This paper concentrates on the analysis of a category of coupled Langevin‐type pantograph differential equations involving the generalized Caputo fractional derivative with nonlocal conditions. We conduct this analysis in two cases for the second member in the nonlinear function; in other words, for the real space R and an abstract Banach space Θ.

A Counterexample for Singular Equations with Indefinite Weight

open access: yesAdvanced Nonlinear Studies, 2017
We construct a second-order equation x¨=h⁢(t)/xp{\ddot{x}=h(t)/x^{p}}, with p>1{p>1} and the sign-changing, periodic weight function h having negative mean, which does not have periodic solutions.

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

open access: yesBoundary 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

open access: yesAdvanced 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 ...
