Breakdown of a 2D Heteroclinic Connection in the Hopf-Zero Singularity (I) [PDF]

open access: yesJournal of Nonlinear Science, 2018
In this paper we study a beyond all order phenomenon which appears in the analytic unfoldings of the Hopf-zero singularity. It consists in the breakdown of a two-dimensional heteroclinic surface which exists in the truncated normal form of this singularity at any order.

Topologically crossing heteroclinic connections to invariant tori

open access: yesJournal of Differential Equations, 2003
Let \(M\) be a symplectic manifold of dimension \(2n_c+ 2n_h\), with \(n_c\), \(n_h> 0\), and let \(f_\mu: M\to M\) be a family of symplectic diffeomorphisms that depends smoothly on \(\mu\) with \(|\mu- \mu_0|< a_0\) for some \(a_0> 0\). We assume that each \(f_\mu\) has a partially hyperbolic fixed point \(p_\mu\) such that the derivative of \(f_\mu\)

On the loss of compactness in the vectorial heteroclinic connection problem [PDF]

open access: yesProceedings of the Royal Society of Edinburgh: Section A Mathematics, 2016
We give an alternative proof of the theorem of Alikakos and Fusco concerning existence of heteroclinic solutionsU: ℝ → ℝNto the systemHerea±are local minima of a potentialW∈C2(ℝN) withW(a±) = 0. This system arises in the theory of phase transitions. Our method is variational but differs from the original artificial constraint method of Alikakos and ...

Shapley Polygons in 4 x 4 Games

open access: yesGames, 2010
We study 4 x 4 games for which the best response dynamics contain a cycle. We give examples in which multiple Shapley polygons occur for these kinds of games.

Robust sequential working memory recall in heterogeneous cognitive networks

open access: yesFrontiers in Systems Neuroscience, 2014
Psychiatric disorders are often caused by partial heterogeneous disinhibition in cognitive networks, controlling sequential and spatial working memory (SWM).

A complex network perspective on brain disease. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT If brain anatomy and dynamics have a complex network structure as it has become standard to posit, it is reasonable to assume that such a structure should play a key role not only in brain function but also in brain dysfunction. However, exactly how network structure is implicated in brain damage and whether at least some pathologies can be ...

Saddle-center and periodic orbit: Dynamics near symmetric heteroclinic connection [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2021
An analytic reversible Hamiltonian system with two degrees of freedom is studied in a neighborhood of its symmetric heteroclinic connection made up of a symmetric saddle-center, a symmetric orientable saddle periodic orbit lying in the same level of a Hamiltonian, and two non-symmetric heteroclinic orbits permuted by the involution.

The Contrast Structures for a Class of Singularly Perturbed Systems with Heteroclinic Orbits

open access: yesDiscrete Dynamics in Nature and Society, 2016
Singularly perturbed problems are often used as the models of ecology and epidemiology. In this paper, a class of semilinear singularly perturbed systems with contrast structures are discussed.
