Working over the complex field isn't significant for this kind of question, only the fact that the field is algebraically closed of characteristic 0. The examples mentioned are not very helpful. Also, the question here is algebraic and doesn't require analysis or differential geometry. (It's of course not necessary here to get into the more difficult problems in prime characteristic, but I wanted to emphasize that Steinberg's setting for regular elements is more natural.) | |
