Title:Visual Differential Geometry and the Hyperbolic Plane
Seminar:MASS Colloquium
Speaker:Tristan Needham, University of San Francisco
Abstract:
Differential Geometry" contains the word "Geometry", yet the standard texts are filled with proofs (versus explanations) that are nothing more than ungeometric calculations. We will instead give a few elementary examples of how the concepts and results of this important subject can be made accessible to visual intuition. In particular we will show how this Visual Differential Geometry sheds light on the hyperbolic plane, yielding a simplified proof of the key fact that it has constant negative Gaussian curvature. [No prior knowledge of Differential Geometry will be assumed. Brief prior exposure to Hyperbolic Geometry would be helpful, though even that is not essential.]
