Abstract (EN):
Baraviera and Bonatti (2003 Ergod. Theory Dyn. Syst. 23 1655-70) proved that it is possible to perturb, in the C-1-topology, a stably ergodic, volume-preserving and partially hyperbolic diffeomorphism in order to obtain a non-zero sum of all the Lyapunov exponents in the central direction. In this paper we obtain the analogous result for volume-preserving flows.
