摘要:

本文从类波性态的角度研究了具有散射耗散项和不定常质量项的半线性波动方程的小数据爆破问题。确定了Strauss型临界指数,得到了亚临界和临界情况下的爆破结果及相应的寿命上界估计。对于亚临界情形,我们的论证不依赖于耗散和质量的符号条件,从而推广了\cite{Lai-Sch-Taka18}中的结果。此外,我们给出了临界情形的爆破结果,这是一个新的结果。

英文摘要:

In the present paper, we study small data blow-up of the semi-linear wave equation with a scattering dissipation term and a time-dependent mass term from the aspect of wave-like behavior. The Strauss type critical exponent is determined and blow-up results are obtained to both sub-critical and critical cases with corresponding upper bound lifespan estimates. For the sub-critical case, our argument does not rely on the sign condition of dissipation and mass, which gives the extension of the result in \cite{Lai-Sch-Taka18}. Moreover, we show the blow-up result for the critical case which is a new result.
