SUMMARY

The discussion focuses on finding a Mobius Transformation, denoted as f, that maps the region where the imaginary part of z is greater than 2, specifically Im(z) > 2, to the interior of the circle defined by |w - 2| < 3. Participants confirm that Mobius transformations are determined by three points and preserve orientation. The suggested approach involves selecting three points on the line z = 2 and corresponding points on the circle |w - 2| = 3, ensuring that the half-plane and the circle's interior are oriented correctly.

PREREQUISITES
  • Understanding of Mobius transformations
  • Familiarity with complex analysis concepts
  • Knowledge of geometric transformations
  • Basic skills in mapping regions in the complex plane
NEXT STEPS

  • Learn how to determine the images of points under Mobius transformations
  • Explore geometric interpretations of complex mappings
  • Investigate the significance of orientation preservation in transformations
USEFUL FOR

Mathematicians, students of complex analysis, and anyone interested in geometric transformations in the complex plane.

I'm pretty stuck on this. I need to find a Mobius Transformation f such that

f: \{ z: Im{z}&gt;2 \} \rightarrow \{ w:|w-2|&lt;3 \}

I don't really have any ideas here. My notes aren't really helping here either. Can anybody point me in the right direction?

Do your notes say that Mobius transformations are determined by 3 images and preserve orientation?
 
yes. i think so. how does this help us though?
 
I think this will work: Pick 3 points on the line I am z = 2 that go in a certain direction. Say you pick them such that the half plane is on their right. For their images under the Mobius transformation, pick 3 points on the circle |w - 2| = 3 such that the interior of the circle is also on their right.
