K-D方程的阻尼解

Damping to prevent the blow-up of the Korteweg-de Vries equation

Pierre Garnier

摘要:

研究了一类广义阻尼KdV方程$u_t + u_x + u_{xxx} + u^p u_x + \mathscr{L}_γ(u)= 0$解的性态.我们首先陈述了局部适定性的结果。然后当$p \geq 4$时,给出关于$\mathscr{L}_γ$的条件以防止解爆破。最后,我们数值构建这样的阻尼序列。

英文摘要:

We study the behavior of the solution of a generalized damped KdV equation $u_t + u_x + u_{xxx} + u^p u_x + \mathscr{L}_γ(u)= 0$. We first state results on the local well-posedness. Then when $p \geq 4$, conditions on $\mathscr{L}_γ$ are given to prevent the blow-up of the solution. Finally, we numerically build such sequences of damping.
