Selforthogonal modules with finite injective dimension
收藏 引用
Science China Mathematics 2000年 第11期43卷 1174-1181页
作者: 黄兆泳 Department of Mathematics Beijing Normal University Beijing 100875 China
The category consisting of finitely generated modules which are left orthogonal with a cotilting bimodule is shown to be functorially finite. The notion of left orthogonal dimension is introduced , and then a necessar... 详细信息

Science China Mathematics 2019年 第4期62卷 629-648页
作者: Xuefeng Mao Xudong Gao Yanni Yang Jiahong Chen Department of Mathematics Shanghai University Department of Mathematics College of Mathematics and StatisticsKashgar University
In this paper, we introduce and study differential graded(DG for short) polynomial algebras. In brief, a DG polynomial algebra A is a connected cochain DG algebra such that its underlying graded algebra A~# is a polyn... 详细信息
