Abstract

We extend our work of [J. Algebra 230 (2000) 378-423] on unipotent blocks of classical groups to blocks of orthogonal groups containing characters labelled by degenerate symbols. We also show that, for classical groups in the linear prime case, there are only finitely many Morita types of unipotent blocks with a given defect group. (C) 2004 Elsevier Inc. All rights reserved.
