AlgTop3: Two-dimensional surfaces: the sphere

Описание к видео AlgTop3: Two-dimensional surfaces: the sphere

After the plane, the two-dimensional sphere is the most important surface, and in this lecture we give a number of ways in which it appears. As a Euclidean sphere, we relate it to stereographic projection and the inversive plane.

This is the third lecture in this beginner's course on Algebraic Topology. The lecturer is Assoc Prof N J Wildberger of the School of Mathematics and Statistics at UNSW. His YouTube site Insights into Mathematics at user: njwildberger also contains series on MathFoundations, History of Mathematics, LinearAlgebra, Rational Trigonometry and even one called Elementary Mathematics (K-6) Explained.
