Talk:Aufgaben:Problem 1

The proof that \(\rho(e)=e\) is trivial, but I added it nevertheless. You will most likely lose points of you don't show it at the exam. It is very easy, though.

I dont think it is necessary tho show that \(\rho\) preserves inverses for \(\rho\) to be a homomorphism, but it is certainly not wrong if you do it ;-)

I assume you want to show that \(\rho(g) \in GL(V)\) but I believe this is always implied by: G a group, V a Vector space + homomorphism. So I also don't think it is necessary.
