Stability properties of divergence-free vector fields

C Ferreira - Dynamical Systems, 2012 - Taylor & Francis
A divergence-free vector field satisfies the star property if any divergence-free vector field in
some C 1-neighbourhood has all singularities and all closed orbits hyperbolic. In this article …

Shades of hyperbolicity for Hamiltonians

M Bessa, J Rocha, MJ Torres - Nonlinearity, 2013 - iopscience.iop.org
We prove that a Hamiltonian system H∈ C2 (M, R) is globally hyperbolic if any of the
following statements hold: H is robustly topologically stable; H is stably shadowable; H is …

Generic Hamiltonian Dynamics

M Bessa, C Ferreira, J Rocha, P Varandas - Journal of Dynamics and …, 2017 - Springer
In this paper we contribute to the generic theory of Hamiltonians by proving that there is a C^
2 C 2-residual RR in the set of C^ 2 C 2 Hamiltonians on a closed symplectic manifold MM …

Shadowing, expansiveness and stability of divergence-free vector fields

C Ferreira - Bulletin of the Korean Mathematical Society, 2014 - koreascience.kr
Let X be a divergence-free vector field defined on a closed, connected Riemannian
manifold. In this paper, we show the equivalence between the following conditions: ${\bullet} …

On the entropy of conservative flows

M Bessa, P Varandas - Qualitative Theory of Dynamical Systems, 2011 - Springer
We obtain a C 1-generic subset of the incompressible flows in a closed three-dimensional
manifold where Pesin's entropy formula holds thus establishing the continuous-time version …

Hamiltonian suspension of perturbed Poincaré sections and an application

M Bessa, JL Dias - Mathematical Proceedings of the Cambridge …, 2014 - cambridge.org
We construct a Hamiltonian suspension for a given symplectomorphism which is the
perturbation of a Poincaré map. This is especially useful for the conversion of perturbative …

Generic behaviours of conservative dynamical systems

MJ Torres - 2022 - repositorium.uminho.pt
Dynamical systems is the study of the long-term behaviour of evolving systems. The
foundations were set by the innovative work of Henri Poincaré (1854-1912), Les Méthodes …
