Talk:Aufgaben:Problem 6
From Ferienserie MMP2
In my view, the statement \(Ker(A) \neq 0\) must be a typo in the textbook. I corrected it to \(Ker(A - \lambda 1)\neq 0\)

The "alternative" solution has one typo in b) as \(\rho(g)\) is meant to be unitary (not self-adjoint), therefore there must be an \(rho(g)^{-1}\) in the equation with the scalar product. Apart from that, it's really all the same but more detailed and therefore it might be easier to follow.
