Text

For the core topic of the course, which will be about the geometry and topology of surfaces, we will use Differential Forms and Applications, by M. do Carmo
Springer, 1994

We will supplement the textbook with course notes to be handed out (or made available online) throughout the course.
The notes will contain more than we will actually cover. I will tell in class the relevant sections.

Grading Information

We plan to have 9 weekly homework assignments, one midterm, and one final exam. They will all have the same weight. The exams will be take-home and will not be fundamentally different from the homework sets. The main difference is that I plan to grade the exams mostly myself (with perhaps some TA help) and will likely be more strict in grading them. The mid-term homework-exam will be due 2/20/2015 and the final homework-exam will be due 4/24/2015.

The final score will be the simple mean (with equal weights) of the top 10 scores (adjusted so that the maximal score is 100). This means that you can drop the least score of the 11.



The final score will be translated into a letter grade of A, B, C, D, F (with plus and minus shadings) in a way that is not harsher than the following table (if the grade distribution of the whole class is significantly lower than usual, then "curving" may be considered, but it is unlikely to be needed):

Numerical Range Letter Grade
[85, 100] A
[70, 85) B
[60, 70) C
[50, 60) D
[0, 50) F



In assigning pluses and minuses, I will divide the final scores in each letter roughly evenly. Please note: by this I do not mean, for example, that A- corresponds to the interval [85, 90) or that A corresponds to [90, 95). Rather, the scores in each letter range indicated in the table will be divided in roughly equal numbers so that the number of scores corresponding to A-, A, A+ will be approximately the same. Therefore, the exact grade cut-offs for the signs will not be known until all the scores are in.


Homework

The plan is to have a total of 11 HW/exams assignments. Of these 11, the 10 best scores will count towards the total grade score.

Assignments should be turned in on the due date (Fridays) at the beginning of class.
You are allowed and encouraged to collaborate on your assignments.
Late assignments will not be accepted except under very special circumstances and never after the solutions have been posted.
