| Nov 4, 2018 at 17:58 | comment | added | Kevin Casto | In particular, this says that every irrep can be defined over $\mathbb{Q}(\zeta)$, which is an important consequence (maybe ~equivalent to?) Brauer's induction theorem. | |

| Nov 4, 2018 at 17:40 | comment | added | Benjamin Steinberg | The characteristic 0 case is in Curtis and Reiner. Reiner has a paper maybe in proceedings of the ams doing the modular case with Brauer characters. | |
