摘要

我们研究了三分量卡多姆采夫-彼得维亚什维利（KP）层次结构与三分量修正卡多姆采夫-彼得维亚什维利（mKP）层次结构之间的量规变换。我们介绍了三分量KP层次结构的自动-贝克隆变换，并描述了三分量KP和mKP层次结构的米乌拉变换，即（k=0\to k=1\）。此外，还给出了三分量 mKP 层次的自贝克伦变换。这为三分量KP和mKP层次结构的特征函数上的规规变换产生Miura和auto-Bäcklund变换提供了更有力的证据。

Gauge transformations between three-component KP and three-component mKP hierarchies

We examine the gauge transformations between the three-component Kadomtsev–Petviashvili (KP) hierarchy and the three-component modified Kadomtsev–Petviashvili (mKP) hierarchy. We introduce the auto-Bäcklund transformation of the three-component KP hierarchy and describe the Miura transformation of the three-component KP and mKP hierarchies, that is, \(k=0\to k=1\). Additionally, the auto-Bäcklund transformation of the three-component mKP hierarchy is also given. This provides more powerful evidence that the gauge transformations generate Miura and auto-Bäcklund transformation on the eigenfunctions of the three-component KP and mKP hierarchies.
