報告題目:Integrable systems: what they are and how many? 報 告 人:王敬萍(University of Kent 教授) 報告時間:2020年12月29日 下午5:00開始 報告地點:ZOOM會議鏈接:https://zoom.us/j/7323017223?pwd=RisyVGJteUU3eU50ZlZvdFd1NTZrUT09 Meeting ID: 732 301 7223 Passcode: nbu2021 報告摘要: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. 報告人簡介: 王敬萍,英國肯特大學教授、博士生導師,可積系統領域專家,在國際著名雜志CMP, Theoret. and Math. Phys., Phys. D, Stud. Appl. Math., J. Math. Phys., Nonlinearity, J. Differential Equations, Inverse Problems, J. Nonlinear Sci. 等發表論文五十多篇。
