On the Local Structure of Morita and Rickard Equivalences between Brauer Blocks (Progress in Mathematics)

About this book

1.1 This work began by answering the implicit question that Michel Broué raises in [6, 6.C, (pu 1,2,3)], namely by proving that two blocks have the same defect group and isomorphic source algebras if and only if they are Monta equivalent via a bimodule with trivial source (actually, at that time this answer was already known to Leonard Scott: see Remark 7.5 below).
