We show that if u is a weak solution to the Navier–Stokes initial–boundary value problem with Navier’s slip boundary conditions in QT:=Ω×(0,T), where Ω is a domain in R3, then an associated pressure p exists as a distribution with a certain structure. Furthermore, we also show that if Ω is a “smooth” domain in R3 then the pressure is represented by a function in QT with a certain rate of integrability. Finally, we study the regularity of the pressure in sub-domains of QT, where u satisfies Serrin’s integrability conditions.
