comment Why a holomorphic function satisfying these conditions has to be linear?
There is. It must be from $\Omega$ to $\Omega$, I guess.

comment Consistent branch choice
In this case, the major problem is the formula that doesn't hold, the "branch choice" is a detail that helps explain why it doesn't hold. But the branch choice is of utmost importance to well-define the root, because otherwise we could have different paths yielding different "logarithms" (since, if we don't have a simply connected domain, we can't guarantee that all paths will yield the same integral), thus having multiple "square roots"

comment Show $\ker (\phi)$ is a principal ideal
I didn't know what "height" was, so I looked it up. Why does the kernel has height one?

@Thomas Yes, I would. I'd love if you could tell the problems for $n$ not prime, though.
