On Young modules of general linear groups,  

Abstract:

We study ℓ-permutation modules of finite general linear groups GLn(q) acting on partial flags in the natural module, where the coefficient field of the modules has characteristic ℓ, for ℓandnmid;q. We call the indecomposable summands of these permutation modules linear Young modules. We determine their vertices and Green correspondents, by methods relying only on the representation theory of GLn(q).

Furthermore, we show that when the multiplicative order of q modulo ℓ is st...
