We first introduce various non-Newtonian fluids, and its motivation.

We then address the existence of strong solutions to

a system of equations of

motion of an incompressible non-Newtonian fluid.

Our aim is to prove the short-time existence of

strong solutions for the case of shear thickening viscosity,

which corresponds to the power law

nu(mathbfD)=|mathbfD| q−2
(2<q<+infty)
.

In particular, we find that global strong

solutions exist wheneverq>2.23cdots
.

The results are obtained by flattening the boundary

and by using the difference quotient method.

Near the boundary, we use weighted estimates in the normal direction.
