This Note concerns the regularity up to the boundary of weak solutions to systems describing the flow of generalized Newtonian shear thickening fluids under the homogeneous Dirichlet boundary condition. The extra stress tensor , see (2) below, is given by a power law with shear exponent . Complete proofs of the results presented here are given in the forthcoming paper [4H. Beirão da Veiga, P. Kaplický, M. Růžička, Boundary regularity of shear thickening flows, J. Math. Fluid Mech., in press, doi:10.1007/s00021-010-0025-y
