| Nov 6, 2015 at 14:10 | comment | added | vishmay | What I meant was, if I take the regular representation of $S_n$ it can be decomposed into irreducible corresponding to Young diagrams. My question is whether they remain irreducible under field extensions, in particular $R \to C$. See this related question and answer (I need a reference for this.)mathoverflow.net/questions/185072/… | |
