Mod-05 Lec-11 Möbius transformations (Part I)

[mahmudurrahman]

please publish a course on Electrodynamics by professor V.balakrishnan. What a gem he is. The best ever.

[faithcheboi]

The best lecturer that has helped me understand bilinear transformation

[Steve]

kinds of mob transformations 15:25 and cross ratios 21:30

[mikeCavalle]

incredibly good lecture, indeed --- ( and the camera, mic work is exceptional) --

[samedseven]

a very good explanation. Greets Form germany. Thank you Very much!

[stevel]

Very good lecture, provides nice insight.

We also need to verify that composition must also be associative for it to become a group, not just the closure property of composition.

@19:24, shouldn't it be f(z) = z + b/a? Also, if it is z+-(b/a), how can z be translated to two different points? It's not even a function anymore.

I dont quite understand why Mobius transformation preserve the circle.

Dear Professor, do you know about the origin of the term "Linear Fractional Transformation?" I am just trying to find out who used it first in a written document. I really want to know who put these 3 words together to describe mathematical manipulations. Thank you!
