Global Regularity for a Model of Inhomogeneous Three-dimensional Navier-Stokes Equations

  • 摘要: 考虑一个非均质三维Navier-Stokes方程模型,借助能量方法、Littlewood-Paley仿积分解技巧和Sobolev嵌入定理研究解的整体正则性. 用-D2u近似替代经典非均质Navier-Stokes方程中的耗散项Δu,得到一个新的Navier-Stokes方程模型,其中D是一个傅里叶乘子,其特征是m(ξ)=|ξ|5/4,对于任意小的正常数εδ,当初值(ρ0,u0)∈H3/2×Hδ时,证明了该模型解的爆破准则和整体正则性.
