Math 518 - Differentiable Manifolds I - Fall 2013
The notion of differentiable manifold makes precise the concept of a space which locally looks like the usual euclidean space Rn. Hence, it generalizes the usual notions of curve (locally looks like R1) and surface (locally looks like R2). This course consists of a precise study of this fundamental concept of Mathematics and some of the constructions associated with it: for example, much of the infinitesimal analysis (i.e., calculus) extends from euclidean space to smooth manifolds. On the other hand, the global analysis of smooth manifolds requires new techniques and even the most elementary questions quickly lead to open questions.
If you would like to have a preview of this course and experience a taste of it, you may wish to watch an old recording of 3 lectures by Fields medalist John Milnor.

There will be weekly homework, 1 midterm and a final exam. All exams/midterms will be closed book.
- Homework and in class participation (40% of the grade): Homework problems are to be assigned once a week. They are due the following week, at the beginning of the Friday class. No late homework will be accepted. The two worst homework grades will be dropped. On Fridays, one homework problem will be discussed in class, with the participation of the students and this will be taken into account for the grade.
- Midterm (20% of the grade): The midterm will take place on Friday, October 11, in the regular classroom (the date is subject to change).
- Final Exam (40% of the grade): You have to pass the final to pass the course. According to the non-combined final examination schedule it will take place 7:00-10:00PM, Tuesday, December 17, in the regular classroom.
