报告摘要:Forevery affine Kac-Moody algebra, Drinfeld and Sokolov constructed ahierarchy of integrable systems that generalize the celebratedKorteweg-de Vries (KdV) equation. These integrable hierarchies havevery important application in several areas of mathematical physicslike 2 D topological field theory and Gromov-Witten invariants. Inthis talk, we give a uniform definition of tau function for eachDrinfeld-Sokolov integrable hierarchy associated to affine Kac-Moodyalgebra; moreover, we represent its Virasoro symmetries aslinear/nonlinear actions on the tau function. Based on it, somelatest joint work with Dr. Mattia Cafasso will also be introduced.

 

报告人简介吴朝中博士师从清华大学张友金教授(杰青),博士毕业后赴意大利跟随近代可统创始人之一Dubrovin.B 行博士后研究,2014入中山大学工作.主要从事可Tau函数(日本数学家Sato提出)相关理研究.Adv.Math, IMRN, JPA 等国重要志数篇.

 

报告理论背景:Tau 函数相关理论除了在经典可积系统中研究起着非常重要的作用,目前还在量子可积系统,量子场论,量子群等数学物理前沿理中有重要
