Bifurcation diagrams for singularly perturbed system

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
We consider a singularly perturbed system where the fast dynamic of the unperturbed problem exhibits a trajectory homoclinic to a critical point.

Bifurcations of heteroclinic loops with nonresonant eigenvalues

open access: yesJournal of Mathematics and Computer Science, 2017
Summary: In this paper, we use the way of local coordinates instead of the Floquet method to study the problems of homoclinic and periodic orbits bifurcated from heteroclinic loop for high-dimensional system. Under some transversal conditions and the non-twisted or twisted conditions, we discuss the existence, uniqueness, coexistence, and non ...

The dynamics of a simple Laissez-Faire model with two predators

open access: yesMathematical Biosciences and Engineering, 2008
In this paper, we study the dynamics of a laissez-faire predator--prey model with both a specialist and a generalist predator. We analyze the stabilities of equilibria by performing linearized stability analyses.

Bifurcations of stagnation points in a micropolar fluent media under the influence of an asymmetric peristaltic movement

open access: yesAIP Advances, 2020
In the present analysis, the effects of an asymmetric peristaltic movement on the bifurcations of stagnation points have been investigated. An exact analytic solution for a flow of an incompressible micropolar fluid has been established under long ...

On a codimension $2$ bifurcation of heteroclinic orbits

open access: yesProceedings of the Japan Academy, Series A, Mathematical Sciences, 1987
The author proves under certain conditions the existence of a heteroclinic orbit for the perturbed equation if such heteroclinic orbit exists for the unperturbed equation. From the text: We consider a bifurcation problem of heteroclinic orbits for a family of ODEs on \(\mathbb R^n\).

Bifurcation diagrams for singularly perturbed system: the multi-dimensional case.

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
We consider a singularly perturbed system where the fast dynamics of the unperturbed problem exhibits a trajectory homoclinic to a critical point. We assume that the slow time system admits a unique critical point, which undergoes a bifurcation as a ...

Bifurcation characteristics and safe basin of MSMA microgripper subjected to stochastic excitation

open access: yesAIP Advances, 2015
A kind of magnetic shape memory alloy (MSMA) microgripper is proposed in this paper, and its nonlinear dynamic characteristics are studied when the stochastic perturbation is considered.

Analysis of Tangential Nonlinear Vibration on Machine Hydrostatic Slide

open access: yesShock and Vibration, 2019
In this paper, the nonlinear dynamic responses of the hydrostatic slide were investigated and the effects of damping and external force to control the vibration system were discussed.
