论文摘要
在\ cite {cj}中,作者表明,navier-stokes方程的库奇问题与阻尼$α| u | u |^{β-1} u(α> 0,\;β\ geq1)$具有$ l^2(\ r^3)$中的全局弱解决方案。在本文中,我们证明了$β> 3 $ $ l^2 $中的连续性,也证明了$β\ geq \ geq \ frac {10} 3 $的大时间衰减。使用傅立叶分析和标准技术。
In \cite{CJ}, the authors show that the Cauchy problem of the Navier-Stokes equations with damping $α|u|^{β-1}u(α>0,\;β\geq1)$ has global weak solutions in $L^2(\R^3)$. In this paper, we prove the uniqueness, the continuity in $L^2$ for $β>3$, also the large time decay is proved for $β\geq\frac{10}3$. Fourier analysis and standard techniques are used.
