陈智奇,南开大学数学科学学院教授,博士生导师。研究方向是李群李代数,最近几年主要研究齐性流形上的Einstein度量,相关的研究成果发表于Comm. Anal. Geom.J. Geom. Anal.Ann. Glob. Anal. Geom.Sci.   China Math.等国内外学术期刊。


摘要:In this talk, we give the definition and   classification of generalized Wallach spaces. After that, we recall the study   of Einstein metrics on generalized Wallach spaces and on compact Lie groups   associated with generalized Wallach spaces.



张海诚,南京师范大学数学科学学院副教授。师从清华大学丘成桐数学科学中心邓邦明教授,20176月获理学博士学位。研究方向:代数表示论,主要集中于Hall代数与量子群、李理论之间联系的研究。目前已在J. AlgebraComm. Algebra等杂志上发表SCI论文6篇。


摘要: In this talk, I will briefly review the development   of Hall algebras, starting from Gabriel’s theorem in the representation   theory of quivers. Explicitly, I will give the definitions of Hall algebras   associated to exact categories or triangulated categories (satisfying some finiteness conditions), and definitions of Ringel--Hall   Lie algebras in the sense of Peng--Xiao. If time permits, I will show the   realization of the entire quantum group via Hall algebras of 2-cyclic   complexes.
