Wild oscillations in a nonlinear neuron model with resets: (II) Mixed-mode oscillations [PDF]

, 2017
This work continues the analysis of complex dynamics in a class of bidimensional nonlinear hybrid dynamical systems with resets modeling neuronal voltage dynamics with adaptation and spike emission.

C*-algebras associated with reversible extensions of logistic maps [PDF]

, 2010
The construction of reversible extensions of dynamical systems presented in a previous paper by the author and A.V. Lebedev is enhanced, so that it applies to arbitrary mappings (not necessarily with open range).

Orbital stability of Earth Trojans [PDF]

Astronomy & Astrophysics, 2018
The only discovery of Earth Trojan 2010 TK7 and the subsequent launch of OSIRIS-REx have motived us to investigate the stability around the triangular Lagrange points of the Earth, L4 and L5.

Transit timing observations from Kepler - III. : Confirmation of four multiple planet systems by a Fourier-domain study of anticorrelated transit timing variations [PDF]

, 2012
We present a method to confirm the planetary nature of objects in systems with multiple transiting exoplanet candidates. This method involves a Fourier-domain analysis of the deviations in the transit times from a constant period that result from ...

Navigating cognition: Spatial codes for human thinking

Science, 2018
A framework for cognitive spaces Ever since Tolman's proposal of cognitive maps in the 1940s, the question of how spatial representations support flexible behavior has been a contentious topic. Bellmund et al.

STABILIZATION OF DETERMINISTICALLY CHAOTIC SYSTEMS BY INTERFERENCE AND QUANTUM MEASUREMENTS : THE IKEDA MAP CASE [PDF]

, 1998
We propose a method which can effectively stabilize fixed points in the classical and quantum dynamics of a phase-sensitive chaotic system with feedback.

Global bifurcations close to symmetry [PDF]

, 2016
Heteroclinic cycles involving two saddle-foci, where the saddle-foci share both invariant manifolds, occur persistently in some symmetric differential equations on the 3-dimensional sphere.

Effects of an eccentric inner Jupiter on the dynamical evolution of icy body reservoirs in a planetary scattering scenario [PDF]

, 2017
Aims. We analyze the dynamics of small body reservoirs under the effects of an eccentric inner giant planet resulting from a planetary scattering event around a 0.5 M⊙ star. Methods.

Spiralling dynamics near heteroclinic networks [PDF]

, 2013
There are few explicit examples in the literature of vector fields exhibiting complex dynamics that may be proved analytically. We construct explicitly a {two parameter family of vector fields} on the three-dimensional sphere $\EU^3$, whose flow has a ...

Optimal transport and dynamics of expanding circle maps acting on measures [PDF]

, 2013
Using optimal transport we study some dynamical properties of expanding circle maps acting on measures by push-forward. Using the definition of the tangent space to the space of measures introduced by Gigli, their derivative at the unique absolutely ...
