具有高振荡初速度的可压缩Navier-斯托克斯方程的整体适定性

Qionglei Chen, Changxing Miao, Zhifei Zhang

摘要:

Cannone \cite{Cannone}证明了不可压Navier-斯托克斯方程对于一类高振荡数据的整体适定性。本文在临界泛函框架下证明了可压缩Navier-斯托克斯方程的整体适定性,初始值接近稳定平衡点。特别是,这一结果使我们能够构造全局解的高度振荡的初始速度。证明依赖于一个新的估计双曲/抛物系统的对流项。

英文摘要:

Cannone \cite{Cannone} proved the global well-posedness of the incompressible Navier-Stokes equations for a class of highly oscillating data. In this paper, we prove the global well-posedness for the compressible Navier-Stokes equations in the critical functional framework with the initial data close to a stable equilibrium. Especially, this result allows us to construct global solutions for the highly oscillating initial velocity. The proof relies on a new estimate for the hyperbolic/parabolic system with convection terms.
