Global smoothness
Global smoothness
In three space dimensions and time, given a smooth divergence-free initial velocity of finite energy, do there exist a smooth velocity and pressure, globally defined, solving the incompressible Navier–Stokes equations? Prove existence and smoothness, or exhibit a blow-up.
