摘要
本文研究了多维空间的Benjamin-Bona-Mahony-Burgers方程.在解整体存在的前提下,利用能量积分、时频分解等方法,得到此方程柯西问题解的衰减估计,并且此方程的衰减速率与热传导方程的相同.
In this paper,Benjamin-Bona-Mahony-Burgers equation in multi-dimensional space is investigated.When the global solution of this equation with initial data exists,by using methods of energy estimate and time-frequency decomposition,we obtain the decay estimate of the solution,and the decay rate is the same as that of the heat conduction equation.
