In anycase, I have very specific normalization conditions, and just precomposing by rotation does not preserve koebee. I’ll revise my question to make that clear.

However, of course this changes the derivative at the origin I’m wondering if the following statement holds: Is this obviously wrong?

Yamashita : Nonunivalent generalized Koebe function

I thought I was using standard terminology, at least it’s the one used in Conway’s Complex Analysis Volume 2. Here is how I ended up with this statement: Sign up using Email and Password. This is in response to a comment about rotating the Koebe function Email Required, but never shown.

The removed set is shown below in blue:. Sign up or log in Sign up using Google.

I do not understand your comment about the Koebe function in the edit. Braindead 3, 17 But I don’t know if these modified Koebe functions are extremal in the case where the functions are required to fix Sign up using Facebook. Home Questions Tags Users Unanswered.

How does it arise? The removed set is shown below in blue: Are you assuming that the derivative at the origin is equal to one?

Your function should have az also in the numerator. In particular, there is no extremal map.

Koebe function

The extremal case is given by the Koebe function or one of its rotations. In that book, Koebe function and all of its “rotations” are functions of the form I wrote in my edit.

But this function cannot fix 1: Post as a guest Name. It seems like a rather odd condition, unless you are assuming your functions to be real on the real axis. If you are concerned about the consequences of said adjustment, work differently:
