When the group ring of a finite group over a field is serial

Andrei Kukharev, Gena Puninski

We make a list of finite simple groups whose group rings over a given field are serial.

The Ziegler spectrum and Ringel's quilt of the A-infinity plane singularity

Gena Puninski

We describe the Cohen-Macaulay part of the Ziegler spectrum and calculate Ringel's quilt of the category of finitely generated Cohen--Macaulay modules over the A-infinity plane sin…

Idempotent ideals and non-finitely generated projective modules over integral group rings of polycyclic-by-finite groups

Peter A. Linnell, Gena Puninski, Patrick F. Smith

We prove that every non-finitely generated projective module over the integral group ring of a polycyclic-by-finite group G is free if and only if G is polycyclic.
