On certain blocks of Schur algebras
Tan, K. M.
arxiv: Mathematics::Representation Theory | Mathematics::Rings and Algebras
In this paper, what is already known about defect 2 blocks of symmetric groups is used to deduce information about the corresponding blocks of Schur algebras. This information includes Ext-quivers and decomposition numbers, as well as Loewy structures of the Weyl modules, principal indecomposable modules and tilting modules.
