comment $U \subset \mathbb{C}$ open, how do I construct $f$ holomorphic, such that there is no continuation of $f$ on any neighbourhood of $z \in \partial U$?
@LukasGeyer: I was not aware of that. I thought since the geometric series diverges on the boundary of its convergence radius, it can't be analytically continued. Then now I am even more helpless than I was before.

comment Is there a vector space that cannot be an inner product space?
I'm sorry, in all lectures I have attended so far, the inner product is positive by definition, which is why I did not specify it.
