Oleksandr Chvartatskyi, Yuriy Sydorenko

摘要:

本文引入了(2+1)维k-约束KP族的一个新的双向推广((2+1)-BDk-cKPH).这个新的矩阵族推广了(2+1)维k-cKP矩阵族、$(t_A,τ_B)$矩阵族和$(γ_A,σ_B)$矩阵族.(2+1)-BDk-cKPH包含一个新的矩阵(1+1)-k-约束KP层次.还列出了(2+1)-BDk-cKPH的部分成员。特别是,它包含DS系统的矩阵推广,(2+1)维修改Korteweg-de Vries方程和Nizhnik方程。(2+1)-BDk-cKPH还包括Yajima-Oikawa和Melnikov系统的新的矩阵(2+1)维推广。本文还提出了构造(2+1)-BDk-cKPH方程精确解的二元达布变换Dressing方法。作为一个例子,给出了Davey-Stewartson系统向量推广的多孤子解的精确形式。

英文摘要:

We introduce a new bidirectional generalization of (2+1)-dimensional k-constrained KP hierarchy ((2+1)-BDk-cKPH). This new hierarchy generalizes (2+1)-dimensional k-cKP hierarchy, $(t_A,τ_B)$ and $(γ_A,σ_B)$ matrix hierarchies. (2+1)-BDk-cKPH contains a new matrix (1+1)-k-constrained KP hierarchy. Some members of (2+1)-BDk-cKPH are also listed. In particular, it contains matrix generalizations of DS systems, (2+1)-dimensional modified Korteweg-de Vries equation and the Nizhnik equation. (2+1)-BDk-cKPH also includes new matrix (2+1)-dimensional generalizations of the Yajima-Oikawa and Melnikov systems. Binary Darboux Transformation Dressing Method is also proposed for construction of exact solutions for equations from (2+1)-BDk-cKPH. As an example the exact form of multi-soliton solutions for vector generalization of the Davey-Stewartson system is given.
