Web3 de sept. de 2009 · We study bounded ancient solutions of the Navier–Stokes equations. These are solutions with bounded velocity defined in R n × (−1, 0). In two space dimensions we prove that such solutions are either constant or of the form u ( x, t) = b ( t ), depending on the exact definition of admissible solutions.
