论文摘要
我们为kirchhoff方程的解决方案的寿命提供了新的下限，该方程属于Gevrey空间。当初始数据的频谱集中在原点时，这种下限严格改善了经典的情况。
We provide a new lower bound for the life span of solutions to the Kirchhoff equation for which the initial data belongs to the Gevrey space. This lower bound strictly improves the classical one in the case when the frequency spectrum of the initial data is concentrated at the origin.
