Abstract

On the complement of the unit disk B we consider solutions of the equations describing the stationary flow of an incompressible fluid with shear dependent viscosity. We show that the velocity field u is equal to zero provided u | ∂ B = 0 and lim | x | → ∞ | x | 1 / 3 | u ( x ) | = 0 uniformly. For slow flows the latter condition can be replaced by lim | x | → ∞ | u ( x ) | = 0 uniformly. In particular, these results hold for the classical Navier-Stokes case.
