| May 3, 2011 at 8:46 | comment | added | Marc Palm | You might want to look in Weintraub: Representation Theory of Finite Groups on page 125. Construction 2.13 describes how you can compute the irreducible representation of a semidirect product with $H$ abelian. You have to consider a direct sum over the $H$ orbits on $\widehat{K}$ and then the tannakian category of the stabilizer in $H$ of a character, I guess. That includes your example, if $K$ is abelian. | |
