comment Question on Forster's proof of the residue theorem
Thank you very much for your detailed explanation. I forgot to write that the $U_k$'s are chosen so that $U_j \cap U_k = \emptyset$ for $j\neq k$. From this I think that $\epsilon \rightarrow 0$ is not necessary in the last equality because $a_k$ is the only singular point in $U_k$. Am I wrong ?

I didn't know the alternative definition. Thank you for that.
