讲座人介绍:
谢远成博士本科毕业于华中科技大学,2014年在北京大学获得硕士学位,今年六月在俄亥俄州立大学获得博士学位。目前的研究兴趣为与可积系统相关的代数与几何,特别是KP孤立波与奇异代数曲线之间的关系以及单李代数上的Toda系与旗流形间的关系。
讲座内容:
In this talk, I will associate a class of KP solitons with a family of singular space curves indexed by the numerical semigroups 〈l,lm+1,⋯,lm+k〉, m≥1, 1≤k≤l-1. Where some of these curves can be deformed into smooth “space curves”, and they provide canonical models for the l-th generalized KdV hierarchies (KdV hierarchy corresponds to the case l=2). If time permits, we will also see how to construct the space curves from a commutative ring of differential operators in the sense of the well-known Burchnall-Chaundy theory.
