摘要
本文考虑耗散的η方程组初值问题的光滑解.我们得到,对于任意的大初值,如果初始数据离开真空,则初值问题的光滑解一致地(即与时间无关)离开真空.同时给出了整体光滑解存在性与非存在性的结果.
In this paper, the smooth solutions to the initial value problem of p-system with dissipation are considered and the results are obtained as follows. For arbitrary large initial data, if it is away from vacuum, the smooth solutions to the initial value problem are uniformly (namely, independent of time) away from vacuum. The results of both existence and non-existence of global smooth solutions are given simultaneously.
