A note on the integrability of exceptional potentials via polynomial bi-homogeneous potentials

Primitivo B. Acosta-Humánez, Martha Álvarez-Ramírez, Teresinha J. Stuchi

This paper is concerned with the polynomial integrability of the two-dimensional Hamiltonian systems associated to complex homogeneous polynomial potentials of degree of type $…

Breaking the degeneracy in magnetic cataclysmic variable X-ray spectral modeling using X-ray light curves

Diogo Belloni, Claudia V. Rodrigues, Matthias R. Schreiber +12

We present an analysis of mock X-ray spectra and light curves of magnetic cataclysmic variables using an upgraded version of the 3D CYCLOPS code. This 3D representation of the accr…

Non-integrability of the axisymmetric Bianchi IX cosmological model via Differential Galois Theory

Primitivo Acosta-Humánez, Juan J. Morales-Ruiz, Teresinha J. Stuchi

We investigate the integrability of an anisotropic universe with matter and cosmological constant formulated as Bianchi IX models. The presence of the cosmological constant causes…

About simple variational splines from the Hamiltonian viewpoint

Paula Balseiro, Alejandro Cabrera, Teresinha J. Stuchi +1

In this paper, we study simple splines on a Riemannian manifold from the point of view of the Pontryagin maximum principle (PMP) in optimal control theory. The control problem…

The stability of the triangular libration points for the plane circular restricted three-body problem with light pressure

M. Alvarez-Ramírez, J. K. Formiga, R. V. de Moraes +2

We study the fourth-order stability of the triangular libration points in the absence of resonance for the three-body problem when the infinitesimal mass is affected not only by gr…

Homoclinic Chaos in Axisymmetric Bianchi-IX cosmological models with an "ad hoc" quantum potential

G. C. Corrêa, T. J. Stuchi, S. E. Jorás

In this work we study the dynamics of the axisymmetric Bianchi IX cosmological model with a term of quantum potential added. As it is well known this class of Bianchi IX models are…
