一类Navier-Stokes方程的有限时间爆破

Finite time blow up for a Navier-Stokes like equation

Stephen Montgomery-Smith

摘要:

我们考虑一个类似于Navier-斯托克斯方程的方程。我们证明了存在存在于每个Triebel-Lizorkin或Besov空间(因此也存在于每个Lebesgue和索伯列夫空间)中的初始数据,使得在有限时间之后,解不在Triebel-Lizorkin或Besov空间中(因此也不在Lebesgue或索伯列夫空间中)。本文的目的是说明用半群方法求解Navier-斯托克斯方程的局限性。我们还考虑了在Besov空间$\dot B^{-1,\infty}_\infty$中解的存在性。我们在这个空间中,没有合理的解决方案的Navier-Stokes方程的初始数据。

英文摘要:

We consider an equation similar to the Navier-Stokes equation. We show that there is initial data that exists in every Triebel-Lizorkin or Besov space (and hence in every Lebesgue and Sobolev space), such that after a finite time, the solution is in no Triebel-Lizorkin or Besov space (and hence in no Lebesgue or Sobolev space). The purpose is to show the limitations of the so called semigroup method for the Navier-Stokes equation. We also consider the possibility of existence of solutions with initial data in the Besov space $\dot B^{-1,\infty}_\infty$. We give initial data in this space for which there is no reasonable solution for the Navier-Stokes like equation.
