# Topology I: smooth manifolds

## Course information

Code: MAT1300F

Instructor: Marco Gualtieri, office hours by appointment.

Class schedule: Th2-4 and F2-3

Schedule changes: No class on Sept. 15 and 16: class time will be rescheduled.

Teaching assistant: Francis Bischoff

Evaluation: The final grade is a/2 + t/4 + f/4, where a is the
average of the four best assignment grades, t is the term exam grade, and f is the final exam grade, all out of 100.

Qualifying exam: If the average of your grades from MAT1300F and
MAT1301S is at least A-, you will be exempt from the Topology
qualifying exam.

Term Exam: Thursday, November 3 in class.

Final Exam: 10 AM on Monday, December 19th in BA6183.

## Course notes

## Assignments

Please discuss the problems, but avoid reading a written solution before you write your own, since these must be original.

Late assignments will not be accepted: please hand in whatever you have at the deadline.

Assignments are marked for correctness, but also clarity. Keep your solutions concise, and make sure the structure of your argument is clear. I suggest that you type out your solutions in LaTeX.

The No B.S. bonus provides a 10% bonus for an assignment with no false statements.

## Suggested references

A textbook is not absolutely necessary, as notes and questions will be provided.
However I recommend the book *Introduction to Smooth Manifolds*, by J. M. Lee.
Other useful texts include:

- Warner’s
