Presenter: 彭联刚 教授
Date: 2020-11-20
Location: 光华东主楼2201
Abstract:

In this talk,several constructions of Ringel-Hall algebras will be introduced respectively from representations of quivers, root category given by derived categories, complexes of representations, and etc. Meanwhile using these kinds of Ringel-Hall algebras, one can realize respectively Kac-Moody Lie algebras, elliptic Lie algebras, and quantum enveloping algebras.
