Hence trhey are direct sums of irreducible representations. So if we can understand irreducible representations, we can undersatnd al representations. | |
| Sep 10, 2011 at 7:44 | comment | added | joseph | @Richard and Geoff: Why should we consider "irreducible representations" of groups? In language of representation theory, the question will be simply "To find faithfull representations of finite groups over $\mathbb{R}$"; not necessarily irreducible. | |
