Characteristics of in-out intermittency in delay-coupled FitzHugh-Nagumo oscillators

open access: yes, 2018
We analyze a pair of delay-coupled FitzHugh-Nagumo oscillators exhibiting in-out intermittency as a part of the generating mechanism of extreme events.

Periodic orbits from nonperiodic orbits on an interval

open access: yesApplied Mathematics Letters, 1997
It is known [\textit{L. S. Block} and \textit{W. A. Coppel}, Dynamics in one dimension. Lect. Notes Math. 1513. Berlin etc.: Springer-Verlag (1992; Zbl 0746.58007)] that for a continuous function on an interval, the existence of a dense orbit implies the existence of infinitely many periodic orbits with prime periods forming an unbounded set.

Existence and Uniqueness of Homoclinic Solution for a Class of Nonlinear Second-Order Differential Equations

open access: yesJournal of Applied Mathematics, 2012
The authors study the existence and uniqueness of a set with 2kT-periodic solutions for a class of second-order differential equations by using Mawhin's continuation theorem and some analysis methods, and then a unique homoclinic orbit is obtained as a ...

Dynamical analysis of an integrated pest management predator–prey model with weak Allee effect

open access: yesJournal of Biological Dynamics, 2019
In this paper, a pest management predator–prey model with weak Allee effect on predator and state feedback impulsive control on prey is introduced and analysed, where the yield of predator released and intensity of pesticide sprayed are assumed to be ...

On the existence of a new type of periodic and quasi-periodic orbits for twist maps of the torus

open access: yes, 2002
We prove that for a large and important class of $C^1$ twist maps of the torus periodic and quasi-periodic orbits of a new type exist, provided that there are no rotational invariant circles (R.I.C's).

Arithmetic and growth of periodic orbits

open access: yes, 1999
We give necessary and sufficient conditions for a sequence to be exactly realizable as the sequence of numbers of periodic points in a dynamical system. Using these conditions, we show that no non-constant polynomial is realizable, and give some conditions on realizable binary recurrence sequences.

Scar Intensity Statistics in the Position Representation

open access: yes, 2005
We obtain general predictions for the distribution of wave function intensities in position space on the periodic orbits of chaotic ballistic systems. The expressions depend on effective system size N, instability exponent lambda of the periodic orbit ...

Periodic Orbits of Isometric Flows [PDF]

open access: yesNagoya Mathematical Journal, 1972
Let M be a compact C∞ Riemannian manifold, X a Killing vector field on M, and φt its 1-parameter group of isometries of M. In this, paper, we obtain some basic properties of the set of periodic points of φt. We show that the set of least periods is always finite, and the set P(X, t) of points of M having least period t for the vector field X is a ...

Chains of rotational tori and filamentary structures close to high multiplicity periodic orbits in a 3D galactic potential

open access: yes, 2011
This paper discusses phase space structures encountered in the neighborhood of periodic orbits with high order multiplicity in a 3D autonomous Hamiltonian system with a potential of galactic type. We consider 4D spaces of section and we use the method of

Periodic orbits in periodic discrete dynamics

open access: yesComputers & Mathematics with Applications, 2008
AbstractWe study the combinatorial structure of periodic orbits of nonautonomous difference equations xn+1=fn(xn) in a periodically fluctuating environment. We define the Γ-set to be the set of minimal periods that are not multiples of the phase period. We show that when the functions fn are rational functions, the Γ-set is a finite set. In particular,
