常Jordan型模

Modules of constant Jordan type

Jon F. Carlson, Eric M. Friedlander, Julia Pevtsova

摘要:

本文对特征为$p > 0$的域$k$上的有限群概型$G$引入了常Jordan型模类.这类模在取直和、张量积、Heller移位和直和项时是闭的,并且包含endovarious模。它包含Auslander-Reiten组件中的所有模块,该组件在类中至少有一个模块。高度非平凡的例子构造使用上同调技术。我们提供的图解表明,有很强的条件,分区是约旦型相关联的一个模块的常数约旦型。

英文摘要:

We introduce the class of modules of constant Jordan type for a finite group scheme $G$ over a field $k$ of characteristic $p > 0$. This class is closed under taking direct sums, tensor products, duals, Heller shifts and direct summands, and includes endotrivial modules. It contains all modules in an Auslander-Reiten component which has at least one module in the class. Highly non-trivial examples are constructed using cohomological techniques. We offer conjectures suggesting that there are strong conditions on a partition to be the Jordan type associated to a module of constant Jordan type.
