Koebe quarter theorem

In that book, Koebe function and all of its “rotations” are functions of the form I wrote in my edit. Your function should have az also in the numerator.

But this function cannot fix 1: In anycase, I have very specific normalization conditions, and just precomposing by rotation does not preserve them.

I’m wondering if the following statement holds: Post as a guest Name. I thought I was using standard terminology, at least it’s the one used in Conway’s Complex Analysis Volume 2.

How does it arise?

It seems like a rather odd condition, unless you are assuming your functions to be real on the real axis. The removed set is shown below in blue:.

Are you assuming that the derivative at the origin is equal to one? I do not understand your comment about the Koebe function in the edit.

In particular, there is no extremal map. This is in response to a comment about rotating the Koebe function Sign up using Email and Password.

Sign up using Facebook. The removed set is shown below in blue: The extremal case is given by the Koebe function or one of its rotations. Here is how I ended up with this statement: Braindead 3, functipn However, of course this changes the derivative at the origin Home Questions Tags Users Unanswered.

I’ll revise my fynction to make that clear. If you are concerned about the consequences of said adjustment, work differently: But I don’t know if these modified Koebe functions are extremal in the case where the functions are required to fix Sign up or log in Sign up using Google.
