Also, you are asking too many questions, so it would help to focus better on the most important one. Concerning the added question for other (presumably simple) algebraic groups, you are asking for a lot here given the many open questions. At least in rank one the basics are known in principle. See Jantzen's book Representations of Algebraic Groups II.2.16 and his references, but note that in higher ranks the crucial details for general or special linear groups are usually unknown. | |
