Deformation rings of Group Representations

JOINT IAS/PU NUMBER THEORY SEMINAR
Topic:Deformation rings of Group Representations
Speaker:Bart de Smit
Affiliation:Universiteit Leiden
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.
