Local formulas for the hydrodynamic pressure and applications

Analysis of PDEs 2015-06-17 v1

Abstract

We provide local formulas for the pressure of incompressible fluids. The pressure can be expressed in terms of its average and averages of squares of velocity increments in arbitrary small neighborhoods. As application, we give a brief proof of the fact that CαC^{\alpha} velocities have C2αC^{2\alpha} (or Lipschitz) pressures. We also give some regularity criteria for 3D incompressible Navier-Stokes equations.
