Analysis of the Stability and Chaotic Dynamics of an Ecological Model

open access: yesComplexity, Volume 2024, Issue 1, 2024.
Modelling has become an eminent tool in the study of ecological systems. Ecological modelling can help implement sustainable development, mathematical models, and system analysis that explain how ecological processes can promote the sustainable management of resources.

Ergodic measures with multi-zero Lyapunov exponents inside homoclinic classes

open access: yes, 2016
We prove that for $C^1$ generic diffeomorphisms, if a homoclinic class $H(P)$ contains two hyperbolic periodic orbits of indices $i$ and $i+k$ respectively and $H(P)$ has no domination of index $j$ for any $j\in\{i+1,\cdots,i+k-1\}$, then there exists a ...

Smooth and non-smooth traveling wave solutions of some generalized Camassa-Holm equations

open access: yes, 2013
In this paper we employ two recent analytical approaches to investigate the possible classes of traveling wave solutions of some members of a recently-derived integrable family of generalized Camassa-Holm (GCH) equations.

Limit Cycles and Local Bifurcation of Critical Periods in a Class of Switching Z2 Equivariant Quartic System

open access: yesDiscrete Dynamics in Nature and Society, Volume 2024, Issue 1, 2024.
In this paper, the limit cycles and local bifurcation of critical periods for a class of switching Z2 equivariant quartic system with two symmetric singularities are investigated. First, through the computation of Lyapunov constants, the conditions of the two singularities to become the centers are determined.

Nonintegrability of an extensible conducting rod in a uniform magnetic field

open access: yes, 2011
The equilibrium equations for an isotropic Kirchhoff rod are known to be completely integrable. It is also known that neither the effects of extensibility and shearability nor the effects of a uniform magnetic field individually break integrability. Here

On Shilnikov's scenario in 3D: Topological chaos for vectorfields of class $C^1$

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
Shilnikov's scenario in $\mathbb{R}^3$ means that the equation $x'=V(x)\in\mathbb{R}^3$ with $V(0)=0$ has a homoclinic solution and the eigenvalues of $DV(0)$ are $u>0$ and $\sigma\pm i\mu$ with ...

Homoclinic orbits in generalized Liénard systems

open access: yesJournal of Mathematical Analysis and Applications, 2005
The author considers the planar Liénard-type system \[ \dot{x}=h(y)-F(x),\; \dot{y}=-g(x), \] where the functions \(F(x)\) and \(g(x)\) are continuous on an open interval \(I\) containing \(0\) and \(h(y)\) is continuous and strictly increasing on \(\mathbb{R}.\) Sufficient conditions are given, under which the system has a homoclinic orbit, i.e., a ...

Exploring the Influence of Oblateness on Asymptotic Orbits in the Hill Three-Body Problem

open access: yesAppliedMath
We examine the modified Hill three-body problem by incorporating the oblateness of the primary body and focus on its asymptotic orbits. Specifically, we analyze and characterize homoclinic and heteroclinic connections associated with the collinear ...

Existence of homoclinic orbits for a class of nonlinear functional difference equations

open access: yesElectronic Journal of Differential Equations, 2016
By using critical point theory, we prove the existence of a nontrivial homoclinic orbit for a class of nonlinear functional difference equations. Our conditions on the nonlinear term do not need to satisfy the well-known global Ambrosetti-Rabinowitz ...

Essential hyperbolicity and homoclinic bifurcations: a dichotomy phenomenon/mechanism for diffeomorphisms

open access: yes, 2010
We prove that any diffeomorphism of a compact manifold can be approximated in topology C1 by another diffeomorphism exhibiting a homoclinic bifurcation (a homoclinic tangency or a heterodimensional cycle) or by one which is essentially hyperbolic (it has
