Talk:Linear algebraic group

From Wikipedia, the free encyclopedia

Thanks for the clarification wrt the Lie groups...I wasn't clear on that. Revolver

What I'm not quite clear on, myself, is the status of the unitary group. The 'unitarian trick' of Weyl is to say that it is Zariski-dense in GL(n,C) - I guess. But in what sense is the unitary group _not_ a real algebraic group?
