Time：27 March 2019,14:00

Location： 海韵实验楼105

Abstract: In this talk I shall introduce my work jointed with LU Ming or LIN Ji on the modified Ringel-Hall algebra of period or bounded complexes of a hereditary abelian category. This is a kind of Ringel-Hall algebras which has a nice structure is related directlyto the Drinfeld double, Green’s formula on Ringel-Hall numbers, the derived Hall algebras etc.
