Contributions to the Geometric and Ergodic Theory of Conservative Flows
Mario Bessa, Jorge Rocha
We prove the following dichotomy for vector fields in a C1-residual subset of volume-preserving flows: for Lebesgue almost every point all Lyapunov exponents equal to zero or its o…
Invariant measures for interval maps with critical points and singularities
Vitor Araujo, Stefano Luzzatto, Marcelo Viana
We prove that, under a mild summability condition on the growth of the derivative on critical orbits any piecewise monotone interval map possibly containing discontinuities and sin…
Lorenz-like chaotic attractors revised
Vitor Araujo, Maria Jose Pacifico
We describe some recent results on the dynamics of singular-hyperbolic (or Lorenz-like) attractors: attractors in this class are expansive and so sensitive with respect to initial…
Hitting Time Statistics and Extreme Value Theory
Ana Cristina Moreira Freitas, Jorge Milhazes Freitas, Mike Todd
We consider discrete time dynamical systems and show the link between Hitting Time Statistics (the distribution of the first time points land in asymptotically small sets) and Extr…
Hamiltonian elliptic dynamics on symplectic 4-manifolds
Mario Bessa, Joao Lopes Dias
We consider C2 Hamiltonian functions on compact 4-dimensional symplectic manifolds to study elliptic dynamics of the Hamiltonian flow, namely the so-called Newhouse dichotomy. We s…
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…
