Quercus will only be used only for announcements and posting grades. By default, you should receive an email every time I post a new announcement on Quercus.

All course materials (Assignments, In-class notes,...) will be posted here on this website.

Here is the syllabus

Book Used and Suggested References

The book that we will (semi-)follow is "Topology" by James Munkres (second edition).

Note that we will not follow the book exactly. Several topics will be discussed during the lectures but not in the book; conversely, several sections in the book will not be covered in lectures. Nonetheless, you are only responsible for the material covered in the lectures and tutorials (unless otherwise stated), and you may use the book as a reference.

The book and the lectures do not substitute for one another. There will be several occasions in which the lectures will deviate from the book; you are encouraged to use the book as an alternative approach to deepen your understanding of the material.

I will upload the in-class notes after each lecture along with the corresponding covered sections in the book. This can be found in the lectures tab.

Here are some other great references:
  • "Introduction to Topological Manifolds" by John Lee
  • "General Topology" by Stephen Willard
  • "Foundations of Topology" by Wayne Patty
  • "Topology Without Tears" by Sidney A. Morris
  • "Counterexamples in Topology" by Steen and Seebach
