非自治孤子族

Non-autonomous soliton hierarchies

Maciej Błaszak, Krzysztof Marciniak, Błażej M. Szablikowski

AI总结:

本研究提出一种构造孤子族可积非自治形变的形式体系,将其表述为李代数上Frobenius可积性条件的初值问题,证明存在形式解并给出两类子代数下的显式解,还应用于三类经典孤子族。

摘要:

本文提出了一种系统构造孤子族可积非自治形变的形式体系。该理论被表述为李代数上相关Frobenius可积性条件的初值问题(IVP)。研究表明该初值问题存在形式解,并在遗传李代数的两个特定子代数框架下给出了该形式解的显式形式。最后,将该形式体系应用于Korteveg-de Vries、色散水波以及Ablowitz-Kaup-Newell-Segur孤子族。

英文摘要:

A formalism of systematic construction of integrable non-autonomous deformations of soliton hierarchies is presented. The theory is formulated as an initial value problem (IVP) for an associated Frobenius integrability condition on a Lie algebra. It is showed that this IVP has a formal solution and within the framewrok of two particular subalgebras of the hereditary Lie algebra the explicit forms of this formal solution are presented. Finally, this formalism is applied to Korteveg-de Vries, dispersive water waves and Ablowitz-Kaup-Newell-Segur soliton hierarchies.
