部分耗散双曲平衡律组的整体经典解

Global classical solutions for partially dissipative hyperbolic system of balance laws

Jiang Xu, Shuichi Kawashima

摘要:

本文研究了任意空间维数下的($N$ -分量)双曲平衡律系统.在熵耗散假设和Shizuta-Kawashima代数条件下,在临界正则的Chemin-Lerner空间框架下建立了经典解适定性的一般理论.要做到这一点,我们首先探讨的功能空间理论和发展的基本事实,表明齐次和非齐次Chemin-Lerner的空间之间的关系。然后,这一事实允许证明一般数据的局部适定性和小数据的全局适定性通过使用傅立叶频率局部化参数。最后,我们将新的存在性理论应用于一个具体的流体模型--带阻尼的可压缩Euler方程,并在临界空间得到了相应的结果。

英文摘要:

This work is concerned with ($N$-component) hyperbolic system of balance laws in arbitrary space dimensions. Under entropy dissipative assumption and the Shizuta-Kawashima algebraic condition, a general theory on the well-posedness of classical solutions in the framework of Chemin-Lerner's spaces with critical regularity is established. To do this, we first explore the functional space theory and develop an elementary fact that indicates the relation between homogeneous and inhomogeneous Chemin-Lerner's spaces. Then this fact allows to prove the local well-posedness for general data and global well-posedness for small data by using the Fourier frequency-localization argument. Finally, we apply the new existence theory to a specific fluid model-the compressible Euler equations with damping, and obtain the corresponding results in critical spaces.
