Navier-斯托克斯方程解的定量下界

Quantitative lower bound for lifespan for solution of Navier-Stokes equations

E. Ostrovsky, L. Sirota

摘要:

当初始函数属于相应的Lebesgue-Riesz空间时,我们得到了全空间中Navier-斯托克斯方程的多维初值问题解的寿命的一个简单的定量下界,并在某些重排不变空间中给出了解的先验估计.

英文摘要:

We find a simple quantitative lower bound for lifespan of solution of the multidimensional initial value problem for the Navier-Stokes equations in whole space when the initial function belongs to the correspondent Lebesgue-Riesz space, and give some a priory estimations for solution in some rearrangement invariant spaces.
