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.
