非圆柱区域中具有非线性耗散的阻尼wave equations的注记

A note on damped wave equations with a nonlinear dissipation in non-cylindrical domains

Lingyang Liu

摘要:

本文研究了非圆柱区域上一类具有非线性耗散项的波动方程的长时间行为。这里我们得到的结果放宽了\cite{alb}和\cite{ha}中的非线性项系数(精确地说,即$β(t)|u|^ρu$)的条件(要求$β(t)$为常数或$β(t)$随时间$t$减小),并且对定义区域的限制较少。

英文摘要:

In this paper, we study the large time behavior of a class of wave equation with a nonlinear dissipation in non-cylindrical domains. The result we obtained here relaxes the conditions for the nonlinear term coefficients (in precise, that is $β(t)|u|^ρu$) in \cite{alb} and \cite{ha} (which require $β(t)$ to be a constant or $β(t)$ to be decreasing with time $t$) and has less restriction for the defined regions.
