我们证明了N-S方程在n ∈ N,n ∈ 5上的解的能量衰减<$u(t)<$2 = O(t−µ),意味着高阶范数的衰减,例如<$Dα u(t)<$2 = O(t−µ −| α|/2)和u(t)|时间复杂度O(t− n)
We show that an energy decay ∥u(t)∥2 = O(t−µ) for solutions of the Navier–Stokes equations on ℝn, n ≦ 5, implies a decay of the higher order norms, e.g. ∥Dα u(t)∥2 = O(t−µ −|α|/2) and ∥u(t)|∞ = O(t−µ −n/4).
