The existence of infinitely many boundary blow-up solutions to the p-k-Hessian equation

Advanced Nonlinear Studies, 2023
The primary objective of this article is to analyze the existence of infinitely many radial pp-kk-convex solutions to the boundary blow-up pp-kk-Hessian problem σk(λ(Di(∣Du∣p−2Dju)))=H(∣x∣)f(u)inΩ,u=+∞on∂Ω.{\sigma }_{k}\left(\lambda \left({D}_{i}\left({|

The Existence of solutions to nonlinear second order periodic boundary value problems [PDF]

, 2012
We consider existence of periodic boundary value problems of nonlinear second order ordinary differential equations. Under certain half Lipschitzian type conditions several existence results are obtained. As applications positive periodic solutions of some $\phi$-Laplacian type equations and Duffing type equations are investigated.

Existence results for systems of first-order nabla dynamic inclusions on time scales

Arab Journal of Mathematical Sciences, 2019
In this article, we study the existence of solutions to systems of first-order ∇-dynamic inclusions on time scales with terminal or periodic boundary conditions. We employ the method of solution-tube and Kakutani fixed point theorem.

A Counterexample for Singular Equations with Indefinite Weight

Advanced 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.

Investigation of hybrid fractional q-integro-difference equations supplemented with nonlocal q-integral boundary conditions

Demonstratio Mathematica, 2023
In this article, we introduce and study a new class of hybrid fractional qq-integro-difference equations involving Riemann-Liouville qq-derivatives, supplemented with nonlocal boundary conditions containing Riemann-Liouville qq-integrals of different ...

Monotonicity of the period of a non linear oscillator [PDF]

arXiv, 2015
We revisit the problem of monotonicity of the period function for the differential equation $u"-u+u^p=0$ and give a simple proof of recent results of Miyamoto and Yagasaki.

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 ...
