But this function cannot fix 1: Your function should have az also in the numerator. Braindead 3, 17 In that book, Koebe function and all of its “rotations” are functions of the form I wrote in my edit.

I do not understand your comment about the Koebe function in the edit. How does it arise? Email Kebe, but never shown. Is this obviously wrong? The removed set is shown below in blue:. However, of course this changes the derivative at the origin I’ll revise my question to make that clear.

Are you assuming that the derivative at the origin is equal to one? But I don’t know if these modified Koebe functions are extremal in the case where the functions are required to fix The removed set is shown below in kowbe Home Questions Tags Users Unanswered.

In particular, there is no extremal map. It seems like a rather odd condition, unless you are assuming your functions to be real on the real axis. In anycase, I have very specific normalization conditions, and just precomposing by rotation does not preserve them.

The extremal fjnction is given by the Koebe function or one of its rotations. If you are concerned about the consequences of said adjustment, work differently: Here is how I ended up with this statement: Mathematics Stack Exchange works best with JavaScript enabled.

I’m wondering if the following statement holds: This is in response to a comment about rotating the Koebe function I thought I was using standard terminology, at least it’s the one used in Conway’s Complex Analysis Volume 2.
