2-Blocks with minimal nonabelian defect groups II

We determine the structure of 2-blocks with minimal nonabelian defect groups, by making use of the classification of finite simple groups.

Nilpotent blocks of quasisimple groups for odd primes

Abstract We investigate the nilpotent blocks of positive defect of the quasisimple groups for odd primes. In particular, it is shown that every nilpotent block of a quasisimple group has abelian defect groups. A conjecture of Puig concerning the recognition of nilpotent blocks is also shown for these groups.
