  We prove that the Jacquet restriction functor for a parabolic subgroup of a
reductive group over a non-Archimedean local field is right adjoint to the
parabolic induction functor for the opposite parabolic subgroup, in the
generality of smooth group representations on R-modules for any unital ring R
in which the residue field characteristic is invertible.
  Correction: it turned out that the paper contains a mistake (in Lemma 3.4),
which the authors have been unable to fix. This renders the proof of the main
theorem incomplete.
