In anycase, I have very specific normalization conditions, and just precomposing by rotation does not preserve them.

How does it arise? I’ll revise my question to make that clear.

I do not understand your comment about the Koebe function in the edit. This is in response to a comment about rotating the Koebe function But I don’t know if these modified Koebe functions are extremal in the case where the functions are required to fix Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

Your function should have az also in the numerator. The removed set is shown below in blue: Home Questions Tags Users Unanswered. Here is how I ended up with this statement: But this function cannot fix 1: I thought I was using standard terminology, at least functionn the one used in Conway’s Complex Analysis Volume 2.

Koebe function

In that book, Koebe fucntion and all of its “rotations” are functions of the form I wrote in my edit. However, of course this changes the derivative at the origin I’m wondering if the following statement holds: Are you assuming that the derivative at the koebd is equal to one? Braindead 3, 17 If you are concerned about the consequences of said adjustment, work differently: It seems like a rather odd condition, unless you are assuming your functions to be real on the real axis.

The extremal case is given by the Koebe function or one of its rotations.
