Weight 2 blocks of general linear groups and modular Alvis-Curtis duality

Sibylle Schroll, Kai Meng Tan

Published 2007-05-11, updated 2007-10-24Version 2

We obtain the structure of weight 2 blocks and [2:1]-pairs of q-Schur algebras, and compute explicitly the modular Alvis-Curtis duality for weight 2 blocks of finite general linear groups in non-defining characteristic.
