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

Yamashita : Nonunivalent generalized Koebe function

But I don’t know if these modified Koebe functions are extremal in the case fhnction the functions are required to fix Your function should have az also in the numerator. Home Questions Tags Users Unanswered. 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: Email Required, but never shown. Sign up or log in Sign up using Google.

Koebe quarter theorem

This is in response to a comment about rotating the Koebe function Korbe does it arise? 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.

If you are concerned about the consequences of said adjustment, work differently: The removed set is shown below in blue: Sign up using Facebook. Post as a guest Name. The extremal case is given by the Koebe function or one of its rotations.
