Abstract
Let be the ring of integers in a finite extension and be the -points of a -split reductive group defined over with connected centre and split Borel . We show that Breuil's pseudocompact -module attached to a smooth -torsion representation of is isomorphic to the pseudocompact completion of the basechange to Fontaine's ring (via a Whittaker functional ) of the \'etale hull of defined by Schneider and Vigneras. Moreover, we construct a -equivariant map from the Pontryagin dual to the global sections of the -equivariant sheaf on attached to a noncommutative multivariable version of Breuil's whenever comes as the restriction to of a smooth, admissible representation of of finite length.
