Riemann Sphere - Wikipedia - stereographic projection  ## Metadata - Author: **stereographic projection** - Full Title: Riemann Sphere - Wikipedia - Category: #articles - URL: https://en.wikipedia.org/wiki/Riemann_sphere ## Highlights - In mathematics, the Riemann sphere, named after Bernhard Riemann,[1] is a model of the extended complex plane: the complex plane plus one point at infinity. This extended plane represents the extended complex numbers, that is, the complex numbers plus a value {\displaystyle \infty } for infinity. With the Riemann model, the point {\displaystyle \infty } is near to very large numbers, just as the point {\displaystyle 0} is near to very small numbers
