Comparisons between singularity categories and relative stable categories of finite groups
Shawn Baland, Greg Stevenson
We consider the relationship between the relative stable category of Benson, Iyengar, and Krause and the usual singularity category for group algebras with coefficients in a commut…

Module categories for group algebras over commutative rings
Dave Benson, Srikanth B. Iyengar, Henning Krause +1
We develop a suitable version of the stable module category of a finite group G over an arbitrary commutative ring k. The purpose of the construction is to produce a compactly gene…
