|JOINT IAS/PU NUMBER THEORY SEMINAR|
|Topic:||Deformation rings of Group Representations|
|Speaker:||Bart de Smit|
|Date:||Thursday, April 29|
|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.
