报告题目:Integrable systems: what they are and how many? 报 告 人:王敬萍(University of Kent 教授) 报告时间:2020年12月29日 下午5:00开始 报告地点:ZOOM会议链接:https://zoom.us/j/7323017223?pwd=RisyVGJteUU3eU50ZlZvdFd1NTZrUT09 Meeting ID: 732 301 7223 Passcode: nbu2021 报告摘要:Integrable systems belong to an exceptional class of nonlinear equations, which can be studied with the same completeness as linear systems, at least in principle. They possess a rich set of exact solutions and many hidden properties. Classification of integrable equations is a central problem. There are many approaches to this problem, among which the symmetry approach has proved to be very efficient and powerful. In this talk, I'll give a brief account of recent development of the symmetry approach. The progress has been achieved mainly due to a symbolic representation of the ring of differential polynomials, which enables us to use results from algebraic geometry and number theory. 报告人简介: 王敬萍,英国肯特大学教授、博士生导师,可积系统领域专家,在国际著名杂志CMP, Theoret. and Math.
