Sections 1 and 2 contain an introduction, notation and definitions and basic properties of used function spaces and operators. A pressure, associated with a weak solution to the Navier-Stokes equations for incompressible fluid, is constructed in section 3. The interior regularity of the pressure in regions, where the velocity satisfies Serrin's integrability conditions, is studied in section 4. Finally, section 5 is devoted to criteria of regularity for weak solutions to the Navier-Stokes equations, formulated in terms of the pressure.
