Note: This assignment is NOT required! However, you can complete it for up to 15% extra credit. Or, you can do this one instead of some of the other assignments. Overall, you just need to be sure you completed A0 and A1, as well as 3 of the assignments A2–A6 (your choice which ones). Also, you cannot use late days on this assignment since it’s the last one.
In this assignment, you will investigate tools for working with tangent vector fields on surfaces. Tangent vector fields are central to classical differential geometry, and have many interesting applications. For this homework, we’ll look at one algorithm for designing vector fields, and along the way we’ll cover a lot of deep facts about surfaces.
There’s no PDF this week since the exercises are all from the notes. The notes will also give you all the background you’ll need to complete this assignment. It builds on a lot of the stuff we’ve already done in the class, especially discrete exterior calculus and the Laplacian.
Do any 12 of Exercise 8.1 – Exercise 8.21 in the notes, except for Exercise 8.13.
Submission Instructions. Please submit your solutions to the exercises (whether handwritten, LaTeX, etc.) as a single PDF file by email to Geometry.Collective@gmail.com. This email must also contain the .zip file for your coding solution. Scanned images/photographs can be converted to a PDF using applications like Preview (on Mac) or a variety of free websites (e.g., http://imagetopdf.com). Your submission email must include the string DDG20A6 in the subject line.
Warning: You cannot use late days on this assignment since it’s the last one.
