On the Christensen-Wang Bounds for the Ghost Number of a P-Group Algebra
(Walter de Gruyter Gmbh, 2016) Aksu, Fatma Altunbulak; Green, David J.
Christensen and Wang give conjectural upper and lower bounds for the ghost number of the group algebra of a p-group. We apply results of Koshitani and Motose on the nilpotency index of the Jacobson radical to prove the upper bound and most cases of the lower bound.

(Academic Press inc Elsevier Science, 2017) Aksu, Fatma Altunbulak; Green, David J.
We prove that the group algebra of the quaternion group Q(8) over any field of characteristic two has ghost number three. (C) 2016 Elsevier Inc. All rights reserved.
