Nikita Semenov, Maksim Zhykhovich: Integral motives, relative Krull-Schmidt principle, and Maranda-type theorems

Submission: 2014, Jan 8

In the present article we investigate properties of the category of the integral Grothendieck-Chow motives over a field. We discuss the Krull-Schmidt principle for integral motives, provide a complete list of the generalized Severi-Brauer varieties with indecomposable integral motive, and exploit a relation between the category of motives of twisted flag varieties and integral p-adic representations of finite groups.
