CATALOG DESCRIPTION:

Math 01.507 Differential Geometry                                                                                                                       3 s.h.
(Prerequisites: Math 01.210 and Math 01.230 or permission of instructor)

This course explores the application of calculus towards the study of higher-dimensional surfaces and their geometry. Topics include geodesics, tangent space, directional derivative, Riemannian metrics, isometries, Gaussian curvature, first and second fundamental forms, Gauss-Bonnet Theorem, minimal surfaces, differential manifolds, connections, and Riemannian curvature tensors. Special topics (at the discretion of the instructor) may include Lie groups, symmetric spaces, general relativity, cohomology, and complex geometry. Students will be required to use a computer algebra system to gain geometric intuition.

OBJECTIVES:

Students in this course will learn how the concepts of calculus can be applied to understand the geometry of mathematical surfaces such as planes, spheres, hyperbolic spaces and manifolds in general. Topics include geodesics, tangent space, directional derivative, Riemannian metrics, isometries, Gaussian curvature, first and second fundamental forms, Gauss-Bonnet Theorem, minimal surfaces, differential manifolds, connections, and Riemannian curvature tensor. Special topics (at the discretion of the instructor) may include Lie groups, symmetric spaces, general relativity, cohomology, and complex geometry. Students will be required to use a computer algebra system to solve problems and gain geometric intuition.
