Symmetric group blocks of small defect
Gordon James, Andrew Mathas
This paper is an attempt to compute the decomposition numbers of the blocks of the symmetric group which have "small defect"; that is, blocks of weight smaller than the characteris…

Equating decomposition numbers for different primes
Gordon James, Andrew Mathas
This paper shows that certain decomposition numbers for the Hecke algebras and q-Schur algebras at different roots of unity in characteristic zero are equal. To prove our results w…
