Joined an equation that had been broken across lines, changing its meaning. Also added links (and an erratum) and fixed some punctuation.

| Jun 6, 2011 at 6:43 | comment | added | th.ng | I edited my post, but concerning the fact that the fixed torus is probably of maximal split rank, I can't say it is in the setting of proof... but maybe I'm wrong. | |

| Jun 5, 2011 at 22:29 | comment | added | Jim Humphreys | It would help to specify the specific source you are reading, which is presumably close to the work on the Deligne-Lusztig virtual characters of finite groups of Lie type (Annals of Mathematics, 1976) as developed in many later papers and presented in the books by Carter and Digne-Michel. Earlier foundations for the maximal tori relative to Frobenius action were laid by Steinberg. In your question, the fixed torus is probably meant to be of maximal split rank over the finite field, whereas the twisted torus is meant to be ``minisotropic''? | |
