I really need a hint :/ I have been trying all night to solve 5 through 10 but simply can't get started. And I need to hand in tomorrow :(

Any hints/advice would be welcome. :) - Mar 26th 2014, 10:05 AMjohngRe: Non-commutative algebra - Character theory
Hi,

1. You confessed that this is a homework assignment. We do not do your homework for you.

2. Your question is ill posed. Who is the underlying field K? characteristic 0, algebraically closed? etc. If K has characteristic p, the whole question is moot since there is only one irreducible representation of a p group.

3. For part 5, the character group of G/G' is isomorphic to G/G', so ??

4. There are no questions 6 through 10.
