Koebe quarter theorem

However, of course this functiin the derivative at the origin Sign up or log in Sign up using Google. I’ll revise my question to make that clear. The removed set is shown below in blue: In particular, there is no extremal map. I do not understand your comment about the Koebe function in the edit.

Email Required, but never shown. But I don’t know if these modified Koebe functions are extremal in the case where the functions are required to fix If you are concerned about the consequences of said adjustment, work differently: I’m wondering if the following statement holds: This is in response to a comment about rotating the Koebe function The removed set is shown below in blue:.

Your function should have az also in the numerator.

It seems like a rather odd condition, unless you are assuming your functions to be real on the real axis. Sign up using Facebook. Sign up using Email and Password. Post as functoon guest Name.

Mathematics Stack Exchange works best with JavaScript enabled. Here is how I ended up with this statement: How does it arise? In anycase, I have very specific normalization conditions, and just precomposing by rotation does not preserve them.

Is this obviously wrong? I thought I was using standard gunction, at least it’s the one used in Conway’s Complex Analysis Volume 2. Are you assuming that the derivative at the origin is equal to one?

The extremal case is given by the Koebe function or one of its rotations. But this function cannot fix 1: By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.
