But I don’t know if these modified Koebe functions are extremal in the case where the functions are required to fix Mathematics Stack Exchange works best with JavaScript enabled.

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

Koebe quarter theorem

I’ll revise my question to make that clear. But this function cannot fix 1: How does it arise? Home Questions Tags Users Unanswered. In particular, there is no extremal map.

In that book, Koebe function and all of its “rotations” are functions of the form I wrote in my edit. It seems like a rather odd condition, unless you are assuming your functions to be real on the real axis.

Koebe function

The extremal case is given by the Koebe function or one of its rotations. Is this obviously wrong? Sign up or log in Sign up using Google.

If you are concerned about the consequences of said adjustment, work differently: Are you assuming that the derivative at the origin is equal to one? Your function should have az also in the numerator. I do not understand your comment about the Koebe function in the edit.

I’m wondering if the following statement holds: However, of course this changes the derivative at the origin Braindead 3, 17 Sign up using Email and Password. I thought I was using standard terminology, at least it’s koebd one used in Conway’s Complex Analysis Volume 2.
