Universal deformation rings and generalized quaternion defect groups
Frauke M. Bleher
We determine the universal deformation ring R(G,V) of certain mod 2 representations V of a finite group G which belong to a 2-modular block of G whose defect groups are isomorphic…

Universal deformation rings for the symmetric group S_5 and one of its double covers
Frauke M. Bleher, Jennifer B. Froelich
Let denote the symmetric group on 5 letters, and let denote a non-trivial double cover of whose Sylow 2-subgroups are generalized quaternion. We determine t…
