Prerequisites: Real analysis in several variables (e.g. the implicit function theorem) and point set topology.

Topics to be covered: Manifolds, tangent vectors, smooth maps, tangent bundles and vector bundles in general, Sard's theorem on the measure of critical values, embedding theorems, vector fields and integral curves, Ehresmann's fibration theorem, transversality, degree theory, Lefshetz fixed-point theorem, Euler characteristic.

Textbooks:

We will cover roughly Chapters 1-3 from Guillemin and Pollack, and Chapters 1-3 and 5 from Spivak. We will not follow either book very closely, so it is important to attend the lectures or get the notes from another student.

Other recommended books:

Grading: 50% homework, 50% final.

Homework: Homework will be assigned every other week and will be due the following Wednesday. The homework assignments will be handed out in class and will also be posted on the web page. You must hand in the homework in class each Wednesday. You are encouraged to talk about the problems with other students, but you should write up the solutions individually. You should acknowledge the assistance of any book, student or professor.

Exam: The final exam will be on Wednesday, December 9, 8am-11am.
