广义立方双色散方程解的渐近性质

本文研究广义立方双色散方程的初边值问题,它包括了几类双色散方程以及Bq,IBq,IMBq方程作为特殊情形,当方程非线性项满足某些条件时,利用等价变换和改进的积分估计法证明了问题整体广义解按时间的指数形式衰减为零。最后,将本文定理结论应用到实际模型中,得到了问题的解具有衰减行为时方程参数应满足的条件。

Cauchy Problem for the Nonlinear Double Dispersive Wave Equation

This paper concerns with the Cauchy problem for the nonlinear double dispersive wave equation. By the priori estimates and the method in [9], It proves that the Cauchy problem admits a unique global classical solution. And by the concave method, we give sufficient conditions on the blowup of the global solution for the Cauchy problem.
