Math 518 - Differentiable Manifolds I - Fall 2020

(section X1)

NOTE: This is the public version of the course webpage. More information is available on the moodle course webpage, accessible only to registered students.

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., differential and integral 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.
The main goals of this course are: 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.
