Course Description and Grading BreakdownThe plan for the course would be covering basic concepts of Riemannian Geometry such as Riemannian metrics, connections, geodesics, curvature, completeness, exponential map, Jacobi fields and so on. We plan to prove the four most fundamental theorems relating curvature and topology: the Gauss-Bonnet theorem (expressing the total curvature of a surface in terms of its topological type), the Cartan–Hadamard theorem (restricting the topology of manifolds of nonpositive curvature), Bonnet’s theorem (giving analogous restrictions on manifolds of strictly positive curvature), and a special case of the Cartan–Ambrose–Hicks theorem (characterizing manifolds of constant curvature).

Riemannian Geometry, Manfredo Do Carmo, ISBN: 978-0817634902. 2. Riemannian Manifolds: An Introduction to Curvature, John M. Lee, ISBN-13: 978-0387983226 (available through the Caltech library here https://www.library.caltech.edu/eds/detail?db=cat04350a&an=caltech.909376.) I will mainly follow from Do Carmo's book during the first half of the term. In the end of the term, I will use John Lee's book more.
Course PoliciesThe due date for homework is Friday 1pm (at the start of class). Collaboration is allowed for the homework but you have to write your own solution. You are allowed to turn in one late homework (without penalty) in the quarter. However, you must inform me about turning in your homework late BEFORE the due date, and you must turn in the late homework within a week of the due date. In general, if the homework is late within a week of the due date, it is still acceptable but will be graded based on 20% points off. Assignments***In case you don't have the textbooks in your hand, I have included the scanned page of the problems appearing in the homework. Collaboration Table
* You may use a computer or calculator while doing the homework, but may not refer to this as justification for your work. For example, "by Mathematica" is not an acceptable justification for deriving one equation from another. Also, since computers and calculators will not be allowed on the exams, it's best not to get too dependent on them. |
