Analytic function proofs
Not what you're looking for?
1). Determine the set A such that
For r > 0 let A ={w, w = exp (1/z) where 0<|z|<r}.
2).Prove that there is no branch of the logarithm defined on G= C-{0}.
( C here is the complex plane).
( Hint: suppose such a branch exists and compare this with the principal branch).
I want detailed proofs and please prove every claim you make and justify every step.
