Decomposition matrices for exceptional groups at d=4
Olivier Dudas, Gunter Malle
We determine the decomposition matrices of unipotent -blocks of defect for exceptional groups of Lie type up to a few unknowns. For this we employ the new cohomologic…
Invariant blocks under coprime actions
Gunter Malle, Gabriel Navarro, Britta Späth
If a finite group acts coprimely as automorphisms on a finite group , then the -invariant Brauer -blocks of are exactly those that contain -invariant irreducibl…
Characters of positive height in blocks of finite quasi-simple groups
Olivier Brunat, Gunter Malle
Eaton and Moretó proposed an extension of Brauer's famous height zero conjecture on blocks of finite groups to the case of non-abelian defect groups, which predicts the smallest no…
A positivity conjecture for the Alvis-Curtis dual of the intersection cohomology of a Deligne-Lusztig variety
Olivier Dudas, Gunter Malle
We formulate a strong positivity conjecture on characters afforded by the Alvis-Curtis dual of the intersection cohomology of Deligne-Lusztig varieties. This conjecture provides a…
