摘要
考虑一类涉及超临界源项的非线性黏弹性双曲方程解的爆破时间下界估计,通过构造带阻尼项的控制函数,利用能量估计方法和Sobolev嵌入定理,得到了该问题解爆破时间的显式下界估计.
We considered estimate of a lower bound of blow-up time for solutions to a class of nonlinear viscoelastic hyperbolic equations involving supercritical source terms.By constructing the control function with damping term,using the mehtod of energy estimate and Sobolev embedding theorem,we obtained an explicit estimate of lower bound of the blow-up time for the solutions to the problem.
