Abstract
In this paper, for the Navier-Stokes equations in a bounded connected polygon or polyhedron \(\Omega \subset R^d\), \(d=2,3\), with a homogenous stress type mixed boundary condition, we establish an a priori estimate for the weak solutions and the existence result without small data and/or large viscosity restriction. And a global uniqueness result is obvious based on the a priori estimate obtained.
