Talk:Modular representation theory

From Wikipedia, the free encyclopedia

Notation - Z₂ isn't the best choice here for the field with two elements, since Brauer lifting (if I have the right term) is a basic thing in the theory and would concern lifting of modular representations, in this case, to representations over the 2-adic integers. So at some later point this would all get confusing. F_p for a [[Galois field] should be better.

I think we should actually add a section on "Brauer lifting" (I've no idea either whether this is the right term, but I think the meaning is quite obvious), Brauer characters etc. My main problem, though, is to fit this into the existing structure of the article, as - for example - the lifting technique is useful for _any_ representation in positive characteristic (and not only if the characteristic divides the group order).

There's a basic technical result on lifting idempotents, isn't there? Charles Matthews 18:49, 29 Apr 2005 (UTC)
