临界Besov空间中二流体Euler- Maxwell equations方程的整体适定性

Global well-posedness in critical Besov spaces for two-fluid Euler-Maxwell equations

Jiang Xu, Jun Xiong, Shuichi Kawashima

摘要:

本文研究了两流体Euler-Maxwell方程在临界Besov空间中的适定性,这与单流体情形不同.我们需要解决的困难主要是由于两个载波之间的非线性耦合和抵消。更准确地说,我们首先在具有临界正则性的Besov空间中得到了与数据有关的Cauchy问题和周期问题的经典解的局部存在性和爆破准则。此外,我们构造的整体存在的经典解的援助不同的能量估计(与单流体的情况相比)提供的初始数据是小的,在一定的规范。最后,我们在正则性较低的Besov空间中建立了平衡点附近整体解的大时间渐近性态。

英文摘要:

In this paper, we study the well-posedness in critical Besov spaces for two-fluid Euler-Maxwell equations, which is different from the one fluid case. We need to deal with the difficulties mainly caused by the nonlinear coupling and cancelation between two carriers. Precisely, we first obtain the local existence and blow-up criterion of classical solutions to the Cauchy problem and periodic problem pertaining to data in Besov spaces with critical regularity. Furthermore, we construct the global existence of classical solutions with aid of a different energy estimate (in comparison with the one-fluid case) provided the initial data is small under certain norms. Finally, we establish the large-time asymptotic behavior of global solutions near equilibrium in Besov spaces with relatively lower regularity.
