AI总结:

该研究针对与恒定磁场和电场兼容的冷等离子体方程二维解,在不同电场假设下分析初始数据对柯西问题经典解全局存在或有限爆破的影响,并重点关注轴对称解类的相关条件。

摘要:

我们考虑一类与恒定磁场和恒定电场兼容的冷等离子体方程的二维解。针对这类解,在关于电场的各种假设下,我们研究了初始数据需满足的条件,这些条件能保证柯西问题经典解在给定时间段内全局存在或发生有限爆破。我们特别关注了具有轴对称性的解类。

英文摘要:

We consider a class of two-dimensional solutions of the cold plasma equations compatible with a constant magnetic field and a constant electric field. For this class, under various assumptions about the electric field, we study the conditions on the initial data that guarantee the global existence of the classical solution of the Cauchy problem for a given period of time or a finite blowup. Particular attention is paid to the class of solutions with axial symmetry.
