I actually don't understand the purpose of the example now…but I think I have to ask that in a different question.

Oh you are right, I didn't caught that either.

I thought $K$ was an infinite rectangle, that is not simply connected?

But the pdf says this "hole" is in $K$, he isn't referring to $0$.

I thought for "hole" they mean the little part of the circle that eats out the $K$

I think you are right since $|exp(st)|$ is real.

@John, oh so you are saying my calculations are right. I got the formula from online notes: people.math.gatech.edu/~ghomi/LectureNotes/LectureNotes14G.pdf
