Novikov-Veselov方程线孤子爆破与稳定性的数值研究

Numerical study of blow-up and stability of line solitons for the Novikov-Veselov equation

A. Kazeykina, C. Klein

摘要:

利用Novikov-Veselov(NV)方程,数值研究了在不同能量参数$ E $水平下,扰动Korteweg-de Vries孤子和局域化初始数据的演化.我们表明,作为$ |E| \to \infty $,NV的行为,正如预期的那样,类似于其正式的限制,Kadomtsev Petviashvili方程。然而,在中间状态,即当$ | E | $不是很大时,可能会出现更多不同的情况,特别是观察到爆破。对爆破机理进行了研究。

英文摘要:

We study numerically the evolution of perturbed Korteweg-de Vries solitons and of well localized initial data by the Novikov-Veselov (NV) equation at different levels of the "energy" parameter $ E $. We show that as $ |E| \to \infty $, NV behaves, as expected, similarly to its formal limit, the Kadomtsev-Petviashvili equation. However at intermediate regimes, i.e. when $ | E | $ is not very large, more varied scenarios are possible, in particular, blow-ups are observed. The mechanism of the blow-up is studied.
