Abstract

The p-rank of a finite p-group is the maximal rank of an abelian subgroup. For odd primes the p-groups of p-rank at most 2 are classified by Blackburn. We use this classification in order to prove Olsson’s Conjecture for all blocks with defect groups of p-rank at most 2 provided p > 3. We also develop general methods which deal with controlled blocks.
