| Dec 21, 2012 at 18:31 | comment | added | David Corwin | I actually really like the first proof and have thought about Galois-theoretic ways to prove (or at least think about how to prove) group-theoretic results. | |
| Oct 13, 2011 at 7:04 | comment | added | Mariano Suárez-Álvarez | The second one is actually a great, non-awfully sophisticated argument :) It is essentially the same as the purely algebraic proof of complete reducibility of finite dimensional modules over a fin. dim. semisimple Lie algebra---in that case, one replaces the coprimality by the action of the Casimir element, a completely parallel argument. | |
