This is exactly the reverse of Cartier's argument, as he uses the invariant-theoretical statement to prove the cohomology of $U_n$ rather than the other way round. (He is doing this for the sake of historical authenticity, I assume - there were no Leray spectral sequences at the time when the cohomology of Lie groups was first computed.) But +1 for a nice application of geometry in algebra. | |
