Pointed fusion systems of blocks
Abstract
The pointed fusion system of a block is a structure consisting of the fusions and relative multiplicities between the local pointed groups associated with a maximal Brauer pair. We show that the pointed fusion system is preserved by splendid Morita equivalences and part of the pointed fusion system is preserved by splendid stable equivalences of Morita type.
