If you have a question about this talk, please contact Chris Parker. Donovan’s conjecture predicts that given a p-group D there are only ﬁnitely many Morita equivalence classes of blocks of group algebras with defect group D. While the conjecture is still open for a generic p-group D, it has been proven in 2014 by Eaton, Kessar, K¨ulshammer and Sambale when D is an elementary abelian 2-group, and in 2018 by Eaton and Livesey when D is any abelian 2-group. The proof, however, does not describe these equivalence classes explicitly. A classiﬁcation up to Morita equivalence over a complete discrete valuation ring \mathcal O has been achieved for D with rank 3 or less, and for D = (C2) This talk is part of the Algebra Seminar series. ## This talk is included in these lists:Note that ex-directory lists are not shown. |
