But this function cannot fix 1: 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 blue:. Are you assuming that the derivative at the origin is equal to one?

However, of course this changes the derivative at the origin I do not understand your comment about the Koebe function in the edit. Your function should have az also in the numerator.

Köbe Function — from Wolfram MathWorld

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

I thought I was using standard funnction, at least it’s the one used in Conway’s Complex Analysis Volume 2.

Is this obviously wrong?

Here is how I ended up with this statement: This is in response to a comment about rotating the Koebe function Email Required, but never shown. How does it arise? Home Questions Tags Users Unanswered.

The extremal case is given by the Koebe function or one of its rotations. Mathematics Stack Exchange works best with JavaScript enabled.

In that book, Koebe function and all of its “rotations” are functions of the form I wrote in my edit. In particular, there is no extremal map. Post as a guest Name.
