Abstract
Regularity properties of solutions to the stationary generalized Stokes system are studied. The extra stress tensor is assumed to have a growth given by some N-function, which includes the situation of p-growth. We show results about differentiability of weak solutions. As a consequence we obtain the gradient L q estimates for the problem. These estimates are applied to the stationary generalized Navier Stokes equations.
