In projective geometry, the xy-plane is supplemented by adding an extra line and homogeneous coordinates are introduced to cope with this line at infinity. If points in the plane are described byby a complex number z = x + iy, then, once again, homogeneous coordinates are convenient. A pair (z1, z2) of complex numbers that are not both zero …

Chapter 3 Riemann sphere and rational maps 3.1 Riemann sphere It is sometimes convenient, and fruitful, to work with holomorphic (or in general continu-ous) functions on a compact space. However, we wish to still “keep” all of C in the space we work on, but see it as a subset of a compact space. There are sequences in C that The Riemann sphere is only a conformal manifold, not a Riemannian manifold. However, if one needs to do Riemannian geometry on the Riemann sphere, the round metric is a natural choice (with any fixed radius, though radius = 1 is the simplest and most common choice).
