G. Ponce et al., GLOBAL STABILITY OF LARGE SOLUTIONS TO THE 3D NAVIER-STOKES EQUATIONS, Communications in Mathematical Physics, 159(2), 1994, pp. 329-341
We prove the stability of mildly decaying global strong solutions to t
he Navier-Stokes equations in three space dimensions. Combined with pr
evious results on the global existence of large solutions with various
symmetries, this gives the first global existence theorem for large s
olutions with approximately symmetric initial data. The stability of u
nforced 2D flow under 3D perturbations is also obtained.
