Idea

The 2-sphere with its canonical structure of a complex manifold is called the Riemann sphere.

As such this is complex projective space β„‚P 1\mathbb{C}P^1.

Properties

The biholomorphisms, i.e. the bijective conformal transformations from the Riemann sphere to itself are the MΓΆbius transformations.
