The teacher II is very responsible. I learned very much on this class. 

Since my direction is dynamics on manifold, and my foundation about differential manifold is weak, so I am very seriously about this class, and finally I got understand most of the intuivative thinkings.

The HW is a little but hard to solve. About 5 problems per 2 weeks. Usually first 2 questions are simple.

This class is open to both graduated students and undergraduated students. If you want to learn more, you definitily go to this class.
