论文摘要
我们考虑了在两个空间维度中的两组分数系统的全局库奇问题。我们在与初始数据相关的辐射场方面给出了小时幅度解决方案的大量时间的标准。
We consider the global Cauchy problem for a two-component system of cubic semilinear wave equations in two space dimensions. We give a criterion for large time non-decay of the energy for small amplitude solutions in terms of the radiation fields associated with the initial data.
