标题： Particles versus fields in PT-symmetrically deformed integrable systems

摘要： 我们回顾了一些关于如何利用PT-对称性（即时间反演和宇称变换的同时作用）来构建新的可积模型的最新成果。一些复值多粒子系统，例如Calogero-Moser-Sutherland模型的变形，被证明自然地源于非线性可积系统的实值场方程。还研究了复值非线性可积场方程的一些变形，其中某些甚至允许紧子波解。通过Painlevé检验建立了各种系统的可积性。 显示英文摘要

摘要： We review some recent results on how PT-symmetry, that is a simultaneous time-reversal and parity transformation, can be used to construct new integrable models. Some complex valued multi-particle systems, such as deformations of the Calogero-Moser-Sutherland models, are shown to arise naturally from real valued field equations of non-linear integrable systems. Deformations of complex non-linear integrable field equations, some of them even allowing for compacton solutions, are also investigated. The integrabilty of various systems is established by means of the Painleve test
