Numerical study of the small dispersion limit of the Korteweg-de Vries equation and asymptotic solutions

T. Grava, C. Klein

摘要:

数值研究了Korteweg-de Vries(KdV)方程$u_t+6uu_x+ε^{2}u_{xxx}=0$对$ε\ll1$的小色散极限,并给出了数值解与全$(x,t)$平面上小$ε$的各种渐近公式的定量比较.数值研究了渐近解的匹配问题。

英文摘要:

We study numerically the small dispersion limit for the Korteweg-de Vries (KdV) equation $u_t+6uu_x+ε^{2}u_{xxx}=0$ for $ε\ll1$ and give a quantitative comparison of the numerical solution with various asymptotic formulae for small $ε$ in the whole $(x,t)$-plane. The matching of the asymptotic solutions is studied numerically.
