Removing zero Lyapunov exponents in volume-preserving flows

چکیده
Baraviera and Bonatti in [1] proved that it is possible to perturb, in the Ctopology, a volume-preserving and partial hyperbolic diffeomorphism in order to obtain a non-zero sum of all the Lyapunov exponents in the central direction. In this article we obtain the analogous result for volume-preserving flows.

Generic Dynamics of 4-dimensional C Hamiltonian Systems
We study the dynamical behaviour of Hamiltonian flows defined on 4-dimensional compact symplectic manifolds. We find the existence of a C-residual set of Hamiltonians for which every regular energy surface is either Anosov or it is in the closure of energy surfaces with zero Lyapunov exponents a.e. This is in the spirit of the Bochi-Mañé dichotomy for area-preserving diffeomorphisms on compact ...
متن کاملContributions to the Geometric and Ergodic Theory of Conservative Flows
We prove the following dichotomy for vector fields in a C-residual subset of volume-preserving flows: for Lebesgue almost every point all Lyapunov exponents equal to zero or its orbit has a dominated splitting. As a consequence if we have a vector field in this residual that cannot be C-approximated by a vector field having elliptic periodic orbits, then, there exists a full measure set such th...
متن کاملDenseness of ergodicity for a class of partially hyperbolic volume-preserving flows
Let P be the set of C1 partially hyperbolic volume-preserving flows with one dimensional central direction endowed with the C1flow topology. We prove that any X ∈ P can be approximated by an ergodic C2 volume-preserving flow. As a consequence ergodicity is dense in P.

متن کاملThe Lyapunov exponents of generic volume preserving and symplectic systems
We show that the integrated Lyapunov exponents of C volume preserving diffeomorphisms are simultaneously continuous at a given diffeomorphism only if the corresponding Oseledets splitting is trivial (all Lyapunov exponents equal to zero) or else dominated (uniform hyperbolicity in the projective bundle) almost everywhere. We deduce a sharp dichotomy for generic volume preserving diffeomorphisms...
متن کاملOn Essential Coexistence of Zero and Nonzero Lyapunov Exponents
We show that there exists a C∞ volume preserving diffeomorphism P of a compact smooth Riemannian manifold M of dimension 4, which is close to the identity map and has nonzero Lyapunov exponents on an open and dense subset G of not full measure and has zero Lyapunov exponent on the complement of G. Moreover, P |G has countably many disjoint open ergodic components.
