Arbitrarily large $O$ -Morita Frobenius numbers

Michael Livesey

We construct blocks of finite groups with arbitrarily large $O$ -Morita Frobenius numbers. There are no known examples of two blocks defined over $O$ that are no…

On Picard groups of blocks with normal defect groups

Michael Livesey

Let $b$ be a block with normal abelian defect group and abelian inertial quotient. We prove that every Morita auto-equivalence of $b$ has linear source. We note that this improves…
