具有-1/2阶非齐次Sobolev空间中初始角速度的微极流体

Micropolar fluids with initial angular velocities in non-homogeneous Sobolev spaces of order $-1/2$

Pedro Gabriel Fernández Dalgo

AI总结:

本文针对微极流体提出分数阶能量方法,在初始角速度具有-1/2阶负Sobolev正则性的非齐次空间中开展研究,并指出该框架可推广至带粘性的Boussinesq系统,为Navier-Stokes方程耦合变量的奇异性分析提供新工具。

摘要:

本文研究微极流体的分数阶能量方法,从具有负Sobolev正则性的初始角速度出发。对于初始角速度的假设,我们考虑负阶非齐次Sobolev范数。这里所研究的-1/2正则性对应于一个简化关联系统的临界尺度,且该一般框架也可应用于带粘性的Boussinesq系统。由于我们的方法不同于基于温和解的方法,并且不依赖于投影系统,本工作为研究Navier-Stokes方程中耦合变量的Caffarelli-Kohn-Nirenberg奇异性理论提供了新的工具。

英文摘要:

In this paper, we investigate fractional energy methods for Micropolar fluids, starting with an initial angular velocity of negative Sobolev regularity. For the initial angular velocity assumption, we consider a non-homogeneous Sobolev norm of negative order. The regularity -1/2 studied here corresponds to the critical scaling of a simplified associated system, and the general framework can also be applied to the Boussinesq system with viscosity. Since our approach differs from those based on mild solutions and does not rely on a projected system, this work provides new tools for studying the Caffarelli-Kohn-Nirenberg theory of singularities in coupled variables within the Navier-Stokes equations.
