Explore the revolutionary developments in 19th-century algebraic curve theory in this 58-minute math history lecture. Delve into the introduction of homogeneous coordinates, projective geometry concepts, and the use of complex numbers in curve analysis. Discover how Bernhard Riemann connected the topology of complex curves with their arithmetic properties. Examine key topics including stereographic projection, the Riemann sphere, circular points at infinity, Laguerre's projective angle description, complex number curves, and Riemann surface genus. Gain insight into how this fusion of projective geometry, algebra, and topology laid the foundation for modern algebraic geometry.
