“Counting Wedderburn components of finite group algebras over Q_p”
Abstract: Let b be a block idempotent of the finite group algebra Z_p G. We present a conjecture that expresses the number of Wedderburn components of Q_p G of a given “type” as an alternating sum of those numbers for blocks associated with b on p-local subgroups. We prove that this conjecture is equivalent to a refinement of Alperin’s weight conjecture due to Turull and that it holds for various classes of blocks. This is joint work with Burkhard Külshammer.
