论文摘要
在研究组代数或其块模块类别的派生类别的结构时，对支持$τ$的模块进行分类至关重要。 Koshio和Kozakai表明，在适当的条件下，可以将支撑$τ$施用模块的结构减少到其亚组的结构。我们表明，在适当条件下，“减少商”也有效。
In studying the structure of derived categories of module categories of group algebras or their blocks, it is fundamental to classify support $τ$-tilting modules. Koshio and Kozakai showed that the structure of support $τ$-tilting modules over blocks of finite groups can be reduced to that of their subgroups under suitable conditions. We show that the 'quotient reduction' is also valid under suitable conditions.
