Jan 7, 2015 at 16:58 comment added Jim Humphreys Can you clarify what you mean by "the classification of these orbits is independent of good characteristic"? For bad primes, one sometimes gets a different number of orbits. Maybe a link to Premet's paper would help. (In his 5.11 Carter gives a survey with references of the unipotent classes and nilpotent orbits for bad $p$.)
