内容摘要:Through the Ringel-Hall algebra approach, one can construct Kac-Moody Lie algebras and some elliptic Lie algebras from the derived categories of some finite dimensional associative algebras. In this talk, the constructions of Hall algebras of some triangulated categories via derived Hall algebras for derived categories will be presented and the relations between them will be characterized. A model to realize the quantum groups globally will be discussed. As an application, a natural algebra homomorphism from the Ringel-Hall algebra of a hereditary algebra to the corresponding quantum cluster algebra will be provided. This gives alternative proofs of some results recently obtained by Berensein and Rupel and enables us to study quantum cluster algebras through Hall algebra approach. This talk is based on joint works with Ming Ding and Fan Xu.
