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 Email and Password.

Koebe function

Here is how I ended up with this statement: This is in response to a comment about rotating the Koebe function However, of course this changes the derivative at the origin In anycase, I have very specific normalization conditions, and just precomposing by rotation does not preserve them.

How does it arise? Mathematics Stack Exchange works best with JavaScript enabled. Are you assuming that the derivative at the origin is equal to one?

If you are concerned about the consequences of said adjustment, work differently: Braindead 3, 17 Post as a guest Name. The removed set is shown below in blue: Is this obviously wrong?

It seems like a rather odd condition, unless you are assuming your functions to be real on the real axis.

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

I’m wondering if the following statement holds: But this function cannot fix 1: I thought I was using standard terminology, at least it’s the one used in Conway’s Complex Fubction Volume 2. Your function should have az also in the numerator. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
