Monotone gradient dynamics and location of stationary (p,q)-configurations
Emilia Petrisor
Exploiting the monotone property of the gradient dynamics of the Frenkel-Kontorova model, we locate in the space of (p,q)-configurations the ordered and unordered stationary states…
Twist number and order properties of periodic orbits
Emilia Petrisor
A less studied numerical characteristic of periodic orbits of area preserving twist maps of the annulus is the twist or torsion number, called initially the amount of rotation. It…
Creation of twistless circles in a model of stellar pulsations
Andreea Munteanu, Enrique Garcia-Berro, Jordi Jose +1
In the present paper, we study the Poincare map associated to a periodic perturbation, both in space and time, of a linear Hamiltonian system. The dynamical system embodies the ess…
Entry and exit sets in the dynamics of area preserving Henon map
E. Petrisor
In this paper we study dynamical properties of the area preserving Henon map, as a discrete version of open Hamiltonian systems, that can exhibit chaotic scattering. Exploiting its…
Complex dynamics in a simple model of pulsations for Super-Asymptotic Giant Branch Stars
Andreea Munteanu, Enrique Garcia-Berro, Jordi Jose +1
When intermediate mass stars reach their last stages of evolution they show pronounced oscillations. This phenomenon happens when these stars reach the so-called Asymptotic Giant B…
