摘要
In this paper, we establish a regularity criterion for the Navier-Stokes system with axisymmetric initial data. It is proved that if the local axisymmetric smooth solution u satisfies parallel to u(theta)1(r <=zeta)parallel to L-alpha((0,T*);L-beta) < infinity for any given zeta > 0, with 2/alpha + 3/beta = 1, 4 <= beta <= 6, then the strong solution keeps smoothness up to time T*.
