Universal deformation rings and tame blocks
Frauke M. Bleher, Giovanna Llosent, Jennifer B. Schaefer
Let k be an algebraically closed field of positive characteristic, and let W be the ring of infinite Witt vectors over k. Suppose G is a finite group and B is a block of kG of infi…
Universal deformation rings and dihedral blocks with two simple modules
Frauke M. Bleher, Giovanna Llosent, Jennifer B. Schaefer
Let k be an algebraically closed field of characteristic 2, and let W be the ring of infinite Witt vectors over k. Suppose G is a finite group and B is a block of kG with a dihedra…
Universal deformation rings for the symmetric group S_4
Frauke M. Bleher, Giovanna Llosent
Let k be an algebraically closed field of characteristic 2, and let W be the ring of infinite Witt vectors over k. Let S_4 denote the symmetric group on 4 letters. We determine the…
