摘要 本文研究了一维空间的BBM-Burgers方程.利用时频分解和能量估计等工具,在解整体存在的前提下,得到了本方程柯西问题解的某些衰减估计. In this paper we study BBM-Burgers equation in one space dimension. Using tools of time-frequency decomposition and energy estimate, when the global solution of this equation with initial data exists, we get some decay estimate of this solution.
