Peter Wittwer Leading order down-stream asymptotics of non-symmetric stationary Navier-Stokes flows in three dimensions (118K, LaTeX) ABSTRACT. We consider stationary solutions of the incompressible Navier-Stokes equations in three dimensions. We give a detailed description of the fluid flow in a half-space through the construction of an inertial manifold for the dynamical system that one obtains when using the coordinate along the flow as a time.
