Characteristic-free resolutions of Weyl and Specht modules
arXiv:1104.1959 · doi:10.1016/j.aim.2012.01.006
Abstract
We construct explicit resolutions of Weyl modules by divided powers and of co-Specht modules by permutational modules. We also prove a conjecture of Boltje-Hartmann on resolutions of co-Specht modules.
