Are you assuming that the derivative at the origin is equal to one? In anycase, I have very specific normalization conditions, and just precomposing by rotation does not preserve them.

In that book, Koebe function and all of its “rotations” are functions of the form I wrote in my edit. Sign up using Email and Password. I’ll revise my question to make that clear.

However, of course this changes the derivative at the origin In particular, there is no extremal map.

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

Your function should have az also in the numerator. I do not understand your comment about the Koebe function in the edit.

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: By using our site, you acknowledge that you have read funvtion understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Is this obviously wrong? If you are concerned about the consequences of said adjustment, work differently:
