Hi, I have a question regarding corollary 2.3. in the uploaded image.
it looks very trivial to me becauese Cauchy's theorem states "if f(z) is holomorphic, its closed loop integral
will be always 0". Is this what the author is trying to say? what's the necesseity of the larger disk D' at here?
Why do we use D'?
