The final exam has been graded and the results have been posted via ScoreReports. The high score was 48/48, the low score was 31.5/48, the median score was 44/48, the mean score was 42.6/48, with the standard deviation of 10.2%. I have also assigned the final course grades. If you are interested in your course grade, please ask me by e-mail and I will e-mail you your course grade. On Monday, May 9, I will hold office hours from 10am to 11:30am. You can come take a look at your final exam then and discuss your course grade as well.

The second midterm has been graded and the results have been posted via Score Reports. Here are the solutions to Midterm 2. Although formal letter grades are not assigned for the midterms, you may approximately interpret the results as follows: A: 24-28; B: 19-23.75; C: 14-18.75. The median score was 24.5/28, the mean score was 24.1/28, with the standard deviation of 14.6%.

The first midterm has been graded and the results have been posted via Score Reports. Solutions are posted below. I do not assign formal letter grades for midterms. However, you may approximately interpret the scores as follows: A: 26-29; B: 22-25.75; C: 17-21.75. For what it's worth, here is some statistical data: the median score was 25/29, the mean score was 25.25/29, with the standard deviation of 8.3%

Brief course description.

The basic tools of differential geometry will be introduced at the undergraduate level, by focusing on examples. This is a good first course for those interested in, or curious about, modern differential geometry, and in applying differential geometric methods to other areas. Note that the course description differs somewhat form the one given in the course catalogue (that is somewhat out of date). The present course has been developed by Professor Stephanie Alexander over the period of several last years. We will largely follow class notes and handouts, rather than the textbook.

1. Manifolds: configuration spaces, differentiable manifolds, tangent spaces, tangent bundles, orientability.
2. Calculus on manifolds: Vector fields, flows, tensor fields.
3. Differential forms and exterior calculus.
4. Integration theory: Generalized Stokes theorem, de Rham cohomology.
5. Riemannian geometry: Riemannian metrics, geodesics.

NOTE: The correct due date for each h/work is the one shown in this web page, NOT the one shown in the pdf file of a particular h/wk (the reason is that I am reusing h/wks from previous years when the semester calendar was different).
