A Lycaon pictus impulsive state feedback control model with Allee effect and continuous time delay
Advances in Difference Equations, 2018 Allee effect (i.e. sparse effect) is active when the population density is small. Our purpose is to study such an effect of this phenomenon on population dynamics.

Analytic normalization of analytically integrable differential systems near a periodic orbit
, 2014 For an analytic differential system in $\mathbb R^n$ with a periodic orbit, we will prove that if the system is analytically integrable around the periodic orbit, i.e.

Convergence of a periodic orbit family close to asteroids during a continuation
Results in Physics, 2020 In this work, we study the continuation of a periodic orbit on a relatively large scale and discover the existence of convergence under certain conditions, which has profound significance in research on asteroids and can provide a total geometric ...

The forcing partial order on a family of braids forced by pseudo-Anosov 3-braids [PDF]
, 2007 Li-York theorem tells us that a period 3 orbit for a continuous map of the interval into itself implies the existence of a periodic orbit of every period. This paper concerns an analogue of the theorem for homeomorphisms of the 2-dimensional disk.

On the Noise-Induced Passage Through an Unstable Periodic Orbit I: Two-Level Model [PDF]
, 2003 We consider the problem of stochastic exit from a planar domain, whose boundary is an unstable periodic orbit, and which contains a stable periodic orbit.

Unstable periodic motion in turbulent flows [PDF]
Nonlinear Processes in Geophysics, 2006 Recently found unstable time-periodic solutions to the incompressible Navier-Stokes equation are reviewed to discuss their relevance to plane Couette turbulence and isotropic turbulence.

Periodic Patterns in Orbits of Certain Linear Cellular Automata [PDF]
Discrete Mathematics & Theoretical Computer Science, 2001 We discuss certain linear cellular automata whose cells take values in a finite field. We investigate the periodic behavior of the verticals of an orbit of the cellular automaton and establish that there exists, depending on the characteristic of the ...

, 2007 We study which and how a periodic orbit in phase space links to both the largest Lyapunov exponent and the expectation values of macroscopic variables in a Hamiltonian system with many degrees of freedom.
