摘要 研究了一类非线性六阶波动方程的Chaucy问题,通过引入一个修正的能量泛函,借助Airy方程的Strichartz估计,在Bourgain空间中证明了这类方程的几乎守恒律. In this paper, we study the Cauchy problem of a nonlinear sixth-order wave equation. We introduce a new modified energy function. By use of the Strichartz estimates of Airy equation, the almost conservation law of this equation is proved in Bourgain space.
