Geometry: Hyperbolic space - the upper half-space and Poincaré disk models. 2nd Year Student Lecture

This second lecture from Jason's geometry course, will describe two more ways to view hyperbolic space: on the upper-half of the plane and on the unit disk. In both cases we will describe the symmetries of the hyperbolic model and its geodesics (the shortest paths between points), and see connections to Möbius transformations in complex analysis.
