Summary

The Riemann sphere is the complex plane with one added point ∞\infty, see the definition. Stereographic projection identifies it with the unit sphere in R3\mathbb{R}^3. It is the natural domain and target of Möbius transformations and of meromorphic functions.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
