Global existence of large solutions to 3-D incompressible Navier-Stokes system

This paper proves that the 3-D Navier-Stokes system has a unique global solution under an assumpution on the initial data. That allow the data to be arbitrarily large in the scale invariant space Ḃ∞,∞⁻¹, which contains all the known spaces in which there is a global solution for small data. Moreover, this result provides various examples of arbitrarily large initial data giving rise to global solutions.
