  • Notes on Donovan's Conjecture for Blocks of Tame Representation Type.
    Manuscript (2001)
    Abstract: We summarize in this note the results on Donovan's conjecture for tame blocks. In particular, we point out that the conjecture holds for blocks with dihedral and semidihedral defect groups, but that the conjecture is still open for blocks with generalized quaternion defect group. The results follow from Erdmann's work on the classification of tame blocks up to Morita equivalence. But for several cases there are no complete proofs in the literature and the aim of these notes is to provide the necessary calculations.
