    • 題目 : The (enhanced) Coxeter Plane: an application of differential equations to Lie theory
    • 日時 : 2019年 6月 18日 (火) 16:30 〜 17:30

he Coxeter Plane is obtained from the root system (of a Lie algebra) by projecting the roots to a certain 2-dimensional plane. The resulting picture was discovered by Coxeter in his investigations of polytopes - but rarely appears in the Lie theory literature. We shall give another description of the Coxeter Plane, arising (in a rather unexpected way) from the theory of ordinary differential equations and integrable systems. This is joint work with Nan-Kuo Ho of National Tsing-Hua University, Taiwan.
