Chinese Annals of Mathematics,Series B 2008年 第6期29卷 585-596页
作者: Jianmin CHEN Yanan LIN School of Mathematical Sciences Xiamen University Xiamen 361005 Fujian China
Abstract The authors introduce an effective method to construct the rational function sheaf κ on an elliptic curve E, and further study the relationship between κ and any coherent sheaf on E. Finally, it is shown t... 详细信息

The double Ringel-Hall algebra on a hereditary abelian finitary length category
收藏 引用
Science China Mathematics 2011年 第2期54卷 381-397页
作者: DOU RuJing LIU QunHua XIAO Jie Academy of Mathematics and Systems Science Chinese Academy of Science Beijing 100190 China Institute for Algebra and Number Theory University of Stuttgart Stuttgart 70569 Germany Department of Mathematical Sciences Tsinghua University Beijing 100084 China
In this paper, we study the category H (ρ) of semi-stable coherent sheaves of a fixed slope ρ over a weighted projective curve. This category has nice properties: it is a hereditary abelian finitary length category.... 详细信息
