一个新的扩展q-变形KP族

A new extended q-deformed KP hierarchy

Runliang Lin, Xiaojun Liu, Yunbo Zeng

摘要:

本文提出了一种构造新的扩展q-变形KP($q$ -KP)族及其Lax表示的方法.这种新的扩展$q$ -KP方程族包含两类具有自洽源的q-变形KP方程,其两种约化给出了具有自洽源的q-变形Gelfand-Dickey方程族和具有自洽源的约束q-变形KP方程族,其中包括两类具有自洽源的q-变形KdV方程和两类具有自洽源的q-变形Boussinesq方程.当$q$为1时,所有这些结果都退化为经典结果。这为构造(2+1)维和(1+1)维q变形孤子方程及其Lax表示提供了一种一般方法。

英文摘要:

A method is proposed in this paper to construct a new extended q-deformed KP ($q$-KP) hiearchy and its Lax representation. This new extended $q$-KP hierarchy contains two types of q-deformed KP equation with self-consistent sources, and its two kinds of reductions give the q-deformed Gelfand-Dickey hierarchy with self-consistent sources and the constrained q-deformed KP hierarchy, which include two types of q-deformed KdV equation with sources and two types of q-deformed Boussinesq equation with sources. All of these results reduce to the classical ones when $q$ goes to 1. This provides a general way to construct (2+1)- and (1+1)-dimensional q-deformed soliton equations with sources and their Lax representations.
