| Feb 19, 2016 at 10:58 | comment | added | A Stasinski | It should be noted that using the maximal torus $T$ etc. is not necessary to develop Deligne-Lusztig theory. No subsequent expositions of the theory that I know of use these objects, and this indicates that the maximal torus $T$ is not particularly helpful mathematically and seems to be mostly an aesthetic choice. In fact, Deligne and Lusztig quickly make a choice (Section 1.7) and most of the subsequent results are worked out using a choice (which of course doesn't matter). | |

Too much conjugation; why is the isomorphism well determined?; Int -> \operatorname{Int}
