Hydrodynamic Limit of the Stationary 
Boltzmann Equation in a Slab
(88K, Ams-TeX)

ABSTRACT.  We study the stationary solution of the
Boltzmann equation in a slab with a constant
external force parallel to the boundary and complete
accommodation condition on the walls at a specified
temperature. We prove that when
the force is sufficiently small there exists a solution which
converges, in the hydrodynamic limit, to a local 
Maxwellian with parameters given by the stationary solution of the
corresponding compressible Navier-Stokes equations with no-slip
boundary  conditions. Corrections to this Maxwellian are obtained
in powers of the Knudsen number with a controlled remainder.
