A remark on the topological stability of symplectomorphisms
Mario Bessa, Jorge Rocha
We prove that the C1 interior of the set of all topologically stable C1 symplectomorphisms is contained in the set of Anosov symplectomorphisms.
On the entropy of conservative flows
Mario Bessa, Paulo Varandas
We obtain a -generic subset of the incompressible flows in a closed three-dimensional manifold where Pesin's entropy formula holds thus establishing the continuous-time versio…
On the Stability of the Set of Hyperbolic Closed Orbits of a Hamiltonian
Mario Bessa, Celia Ferreira, Jorge Rocha
A Hamiltonian level, say a pair of a Hamiltonian and an energy , is said to be Anosov if there exists a connected component of $H^…
Dominated splitting and zero volume for incompressible three-flows
Vitor Araujo, Mario Bessa
We prove that there exists an open and dense subset of the incompressible 3-flows of class C^2 such that, if a flow in this set has a positive volume regular invariant subset with…
