Trans-heteroclinic bifurcation: a novel type of catastrophic shift [PDF]

open access: yesRoyal Society Open Science, 2018
Global and local bifurcations are extremely important since they govern the transitions between different qualitative regimes in dynamical systems. These transitions or tipping points, which are ubiquitous in nature, can be smooth or catastrophic. Smooth

Heteroclinic connections for a class of non-autonomous systems

open access: yesElectronic Journal of Differential Equations, 2001
We prove the existence of heteroclinic connections for a system of ordinary differential equations, with time-dependent coefficients, which is reminiscent of the ODE arising in connection with traveling waves for the Fisher equation.

On the Melnikov function [PDF]

open access: yesریاضی و جامعه, 2023
In this article, we have tried to introduce one of the most important topics in the subject of dynamical systems, namely the Melnikov function, in simple language.

Reconfiguring Smart Structures Using Approximate Heteroclinic Connections in a Spring-Mass Model [PDF]

open access: yes, 2015
Several new methods are proposed to reconfigure smart structures with embedded computing, sensors and actuators. These methods are based on heteroclinic connections between equal-energy unstable equilibria in an idealised spring-mass smart structure ...

A general framework for invasion cycles in ecology. [PDF]

open access: yesEcology
Abstract Theory predicts that indirect interactions in ecological networks sustain species diversity through oscillatory dynamics. However, a framework linking interaction structure to the presence, type, and complexity of these cycles is lacking. Here, we develop an analytical toolbox combining invasion graphs with a mathematical decomposition of ...

Heteroclinic-structure transition of the pure quartic modulation instability

open access: yes, 2022
We show that, in the pure-quartic systems, modulation instability (MI) undergoes heteroclinic-structure transitions (HSTs) at two critical frequencies of {\omega} c1 and {\omega} c2 ( {\omega} c2 > {\omega} c1 ), which indicates that there are ...

Exploration of non-resonant divertor features on the Compact Toroidal Hybrid

open access: yesNuclear Fusion, 2023
Non-resonant divertors (NRDs) separate the confined plasma from the surrounding plasma facing components (PFCs). The resulting striking field line intersection pattern on these PFCs is insensitive to plasma equilibrium effects.

Dynamical Inference of Simple Heteroclinic Networks

open access: yesFrontiers in Applied Mathematics and Statistics, 2019
Heteroclinic networks are structures in phase space that consist of multiple saddle fixed points as nodes, connected by heteroclinic orbits as edges. They provide a promising candidate attractor to generate reproducible sequential series of metastable ...

Spatial dynamics in the family of sixth-order differential equations from the theory of partial formation [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика
Topic of the paper. Bounded stationary (i.e. independent in time) spatially one-dimensional solutions of a quasilinear parabolic PDE are studied on the whole real line.

Heteroclinic orbits between rotating waves of semilinear parabolic equation on the circle [PDF]

open access: yes, 2003
We investigate heteroclinic orbits between equilibria and rotating waves for scalar semilinear parabolic reaction-advection-diffusion equations with periodic boundary conditions.
