Session 14. Group Rings and Related Topics |
Describing unit groups of group rings in small examples |
| Matthias Kuenzer, University of Stuttgart, Germany |
| This talk is based on joint work with Markus Kirschmer |
|
In some small examples, we use a Wedderburn embedding
to describe the unit group of an integral group ring
as an iterated extension of modular groups. The
short exact sequences that occur are induced by
projections to Wedderburn components.
