Dynamics of Unilateral and Bilateral Control Systems with State Feedback for Renewable Resource Management

open access: yesComplexity, 2020
In this paper, mathematical models for the management of biological resources based on a given predator-prey relationship are proposed, and two types of control strategies, unilateral and bilateral control with impulsive state feedback, are studied.

Twisted and Nontwisted Bifurcations Induced by Diffusion

open access: yes, 1996
We discuss a diffusively perturbed predator-prey system. Freedman and Wolkowicz showed that the corresponding ODE can have a periodic solution that bifurcates from a homoclinic loop.

Homoclinic solutions for a class of non-periodic second order Hamiltonian systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2010
We study the existence of homoclinic solutions for the second order Hamiltonian system $\ddot{u}+V_{u}(t,u)=f(t)$. Let $V(t,u)=-K(t,u)+W(t,u)\in C^{1}(\mathbb{R}\times\mathbb{R}^{n}, \mathbb{R})$ be $T$-periodic in $t$, where $K$ is a quadratic growth ...

Study of Stochastic–Fractional Drinfel’d–Sokolov–Wilson Equation for M-Shaped Rational, Homoclinic Breather, Periodic and Kink-Cross Rational Solutions

open access: yesMathematics, 2023
We explore stochastic–fractional Drinfel’d–Sokolov–Wilson (SFDSW) equations for some wave solutions such as the cross-kink rational wave solution, periodic cross-rational wave solution and homoclinic breather wave solution.

Center Manifolds for Homoclinic Solutions

open access: yesJournal of Dynamics and Differential Equations, 2000
In this article, center-manifold theory for homoclinic solutions of ordinary differential equations or semilinear parabolic equations is developed. Here, a center manifold along a homoclinic orbit q(t) is a locally invariant manifold containing all solutions which stay close to q(t) in phase space for all times. Therefore, as usual, the low-dimensional

Full-time dynamics of modulational instability in spinor Bose-Einstein condensates

open access: yes, 2007
We describe the full-time dynamics of modulational instability in F=1 spinor Bose-Einstein condensates for the case of the integrable three-component model associated with the matrix nonlinear Schroedinger equation. We obtain an exact homoclinic solution

Existence of homoclinic orbit in generalized Liénard type system

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
The object of this paper is to study the existence and nonexistence of an important orbit in a generalized Liénard type system. This trajectory is doubly asymptotic to an equilibrium solution, i.e., an orbit which lies in the intersection of the stable ...

Gravity waves from relativistic binaries [PDF]

open access: yes, 1999
The stability of binary orbits can significantly shape the gravity wave signal which future Earth-based interferometers hope to detect. The inner most stable circular orbit has been of interest as it marks the transition from the late inspiral to final ...

Homoclinic solutions for a differential inclusion system involving the p(t)-Laplacian

open access: yesAdvances in Nonlinear Analysis, 2022
The aim of this article is to study nonlinear problem driven by the p(t)p\left(t)-Laplacian with nonsmooth potential. We establish the existence of homoclinic solutions by using variational principle for locally Lipschitz functions and the properties of ...

On the Existence of Localized Excitations in Nonlinear Hamiltonian Lattices

open access: yes, 1994
We consider time-periodic nonlinear localized excitations (NLEs) on one-dimensional translationally invariant Hamiltonian lattices with arbitrary finite interaction range and arbitrary finite number of degrees of freedom per unit cell.
