论文摘要
我们考虑有限群体的置换模块的派生类别,具有积极特征。我们使用Brauer商对此张量三角类别进行分层。我们描述了紧凑型物体的TT光谱的基础,并讨论了几个示例。
We consider the derived category of permutation modules over a finite group, in positive characteristic. We stratify this tensor triangulated category using Brauer quotients. We describe the set underlying the tt-spectrum of compact objects, and discuss several examples.
