Kadomtsev-Petviashvili (KP)层次约简法是推导可积方程显式解的一种突出的直接方法。这种方法是基于Hirota关于可积系统的双线性公式,以及关于可积系统的双线性形式属于KP层次或其扩展的观察。因此,KP层次的解或它的扩展,在适当的约简下,将得到底层可积系统的解。在本文中,我们简要概述了这种KP层次约简方法,用于推导众所周知的可积方程中的孤子、暗孤子、团块和异常波,如KP方程、Korteweg-de Vries方程、Davey-Stewartson方程和非线性Schrödinger方程。
The Kadomtsev–Petviashvili (KP) hierarchy reduction method is a prominent direct method for deriving explicit solutions to integrable equations. This method is based on Hirota’s bilinear formulation of integrable systems, as well as the observation that bilinear forms of integrable systems belong to the KP hierarchy or its extensions. Thus, solutions to the KP hierarchy or its extensions, under proper reductions, would yield solutions to the underlying integrable system. In this article, we give a brief overview of this KP-hierarchy reduction method for the derivation of solitons, dark solitons, lumps and rogue waves in well-known integrable equations, such as the KP equation, the Korteweg–de Vries equation, the Davey–Stewartson equations, and the nonlinear Schrödinger equation.
