## Koebe quarter theorem

How does it arise? I do not understand your comment about the Koebe function in the edit. The extremal case is given by the Koebd function or one of its rotations. It seems like a rather odd condition, unless you are assuming your functions to be real on the real axis.

Post as a guest Name. In that book, Koebe function and all of its “rotations” are functions of the form I wrote in my edit.

I’ll revise my question to make that clear. I’m wondering if the following statement holds: Your function should have az also in the numerator. I thought I was using standard terminology, at least it’s the one used in Koene Complex Analysis Volume 2.

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