Removing zero Lyapunov exponents in volume-preserving flows
Abstract
Baraviera and Bonatti proved that it is possible to perturb, in the c1 topology, 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.
