Energy decay of a class of quasi-linear wave equation
摘要
利用能量扰动法研究了一类拟线性波动方程utt-uxx-β(uxt)x+f(ut)=bu的初边值问题整体解的衰减性,得到了整体解的指数衰减性.
The energy decay for a class of initial boundary value problem of the equation utt-uxx-β（uxt）x＋f（ut）=bu is studied by using a so-called energy perturbation method. The exponential decay of solution is established.
