We provide a new method to compute the Balmer spectra of the bounded derived category and the singularity category of the category algebra of a finite EI category by a decomposition trick due to Stevenson. In particular, we reobtain the result on the singularity category given by Wang under a weaker condition.

类代数上的张量三角分类的谱—一种新方法

我们提供了一种新方法，可通过史蒂文森的分解技巧来计算有限的EI类的类别代数的有界派生类别和奇异类别的Balmer谱。特别是，我们在较弱的条件下重新获得了Wang给出的奇点类别的结果。
