| JOINT IAS/PU NUMBER THEORY SEMINAR | |
| Topic: | Deformation rings of Group Representations |
| Speaker: | Bart de Smit |
| Affiliation: | Universiteit Leiden |
| Date: | Thursday, April 22 |
| Time/Room: | 4:30pm - 5:30pm/Fine Hall -- 214 |
The motivating open question for this talk is to find for a given prime p all local Z_p-algebras which can occur as the deformation ring of some linear representation over F_p of some finite group G. We will show for every p that not all of them are complete intersections. This is joint work with Ted Chinburg and Frauke Bleher.
