Bifurcation of Nongeneric Homoclinic Orbit Accompanied by Pitchfork Bifurcation

Abstract and Applied Analysis, 2014
The bifurcation of a nongeneric homoclinic orbit (i.e., the orbit comes from the equilibrium along the unstable manifold instead of the center manifold) connecting a nonhyperbolic equilibrium is investigated, and the nonhyperbolic equilibrium undergoes ...

Monotone periodic orbits for torus homeomorphisms [PDF]

, 2005
Let f be a homeomorphism of the torus isotopic to the identity and suppose that there exists a periodic orbit with a non-zero rotation vector (p/q,r/q), then f has a topologically monotone periodic orbit with the same rotation vector.Comment: 10 pages, 1

Periodic magnetoconductance fluctuations in triangular quantum dots in the absence of selective probing

, 1998
We have studied the magnetoconductance of quantum dots with triangular symmetry and areas down to 0.2 square microns, made in a high mobility two-dimensional electron gas embedded in a GaAs-AlGaAs heterostructure.

Level spacings and periodic orbits [PDF]

Physical Review E, 2001
Starting from a semiclassical quantization condition based on the trace formula, we derive a periodic-orbit formula for the distribution of spacings of eigenvalues with k intermediate levels. Numerical tests verify the validity of this representation for the nearest-neighbor level spacing (k=0). In a second part, we present an asymptotic evaluation for

GEOPHYSICAL EFFECTS OF THE EARTH'S MONTHLY MOTION

Odessa Astronomical Publications, 2013
The generation of a lunar tidal force is a major geophysical effect of the Earth's monthly motion. It is shown that synoptic processes vary simultaneously with tidal oscillations of the Earth's rotation rate and weather exhibits changes near their ...

Periodic Orbit Quantization beyond Semiclassics

, 1995
A quantum generalization of the semiclassical theory of Gutzwiller is given. The new formulation leads to systematic orbit-by-orbit inclusion of higher $\hbar$ contributions to the spectral determinant.

Kuramoto Phase Model with Inertia: Bifurcations Leading to the Loss of Synchrony and to the Emergence of Chaos

Моделирование и анализ информационных систем, 2015
We consider a finite-dimensional model of phase oscillators with inertia in the case of star configuration of coupling. The system of equations is reduced to a nonlinearly coupled system of pendulum equations.

Periodic orbit theory in fractal drum

, 2005
The level statistics of pseudointegrable fractal drums is studied numerically using periodic orbit theory. We find that the spectral rigidity $\Delta_3(L)$, which is a measure for the correlations between the eigenvalues, decreases to quite small values (

Dynamic Analysis of a Pest Management Smith Model with Impulsive State Feedback Control and Continuous Delay

Mathematics, 2019
In our paper, we propose a single population Smith model with continuous delay and impulsive state feedback control. The application in pest management of this model is investigated.

Periodic solutions with long period for the Mackey–Glass equation

Electronic Journal of Qualitative Theory of Differential Equations, 2020
The limiting version of the Mackey–Glass delay differential equation $x'(t)=-ax(t)+bf(x(t-1))$ is considered where $a,b$ are positive reals, and $f(\xi)=\xi$ for $\xi\in[0,1)$, $f(1)=1/2$, and $f(\xi)=0$ for $\xi> 1$.
