文章研究了一类黏弹性波动方程解在有限时间内爆破的问题,当研究的目标方程解存在爆破时,准确估计爆破时间的下界是本文需要解决的关键问题.通过适当的能量模估计以及定义辅助函数等技术方法,得到了带有黏弹项波动方程解爆破时间的下界.
Abstract
The article studies the problem of blow-up in finite time for a class of viscoelastic wave equations.When the solution of the target equation blow up,accurately estimating the lower bound of the blow-up time is a key issue that needs to address.By em-ploying suitable energy mode estimation and defining auxiliary functions,we obtains the lower bound of the blow-up time of the so-lution to wave equations with viscoelastic terms.
