Cohomology of moduli space of Cubic Fourfolds Ⅰ
收藏 引用
Acta Mathematica Sinica,English Series 2023年 第5期39卷 773-798页
作者: Fei SI Shanghai Research Center For Mathematical Science Shanghai 200433P.R.China
In this paper we compute the cohomology of moduli space of cubic fourfolds with ADE type singularities relying on Kirwan’s blowup and Laza’s GIT construction. More precisely, we obtain the Betti numbers of Kirwan’s... 详细信息

Virtual Manifolds and Localization
收藏 引用
Acta Mathematica Sinica,English Series 2010年 第1期26卷 1-24页
作者: Bohui CHEN Gang TIAN Department of Mathematics and Yangtze Mathematical Center Sichuan University Chengdu 610064 P. R. China Department of Mathematics Peking University Beijing 100084 P. R. China Department of Mathematics Princeton University Princeton New Jersey 08544-1000 USA
In this paper, we explore the virtual technique that is very useful in studying the moduli problem from a differential geometric point of view. We introduce a class of new objects "virtual manifolds/orbifolds', on w... 详细信息

A finite dimensional proof of the Verlinde formula
收藏 引用
Science China Mathematics 2020年 第10期63卷 1935-1964页
作者: Xiaotao Sun Mingshuo Zhou Center of Applied Mathematics School of MathematicsTianjin UniversityTianjin 300072China
We prove two recurrence relations among dimensions Dg(r,d,ω):=dim H^0(UC,ω,ΘUC,ω)of spaces of generalized theta functions on the moduli spaces UC,ω.By using these recurrence relations,an explicit formula(the Verl... 详细信息
