Query: Local null controllability of the N-dimensional Navier-Stokes system
  with N-1 scalar controls in an arbitrary control domain   In this paper we deal with the local null controllability of the
N-dimensional Navier-Stokes system with internal controls having one vanishing
component. The novelty of this work is that no condition is imposed on the
control domain.
