## MAT327 • TOPOLOGY

This is the official homepage for MAT327 at the University of Toronto for the summer 2019 term.
All course information other than grades will be posted here and only here.

# ANNOUNCEMENTS

If you're here because you're curious about how I run this course, please visit my "generic" version of this site for further information.

This website was statically generated from Markdown files by a simple python script I wrote some time ago. It's not fancy, but it gets the job done.

(All course announcements that were here have been moved to the older announcements page. All quizzes, tests, and their solutions are now hidden.)

# LECTURE SUMMARIES

It was suggested that for each lecture I post a short summary of what chapters/sections of my notes are covered in each lecture. This is a great idea, so I'll start doing that here. I'll also be posting any in-class notes from students who wish to make them available for the benefit of other students. I have a tendency to say a lot of things that I don't write on the board in class, so in-class notes may be very valuable.

DISCLAIMER: The in-class notes made by students and published here are the work of students. I have not edited them in detail for mathematical accuracy or style.

### DO YOU WANT TO MAKE YOUR IN-CLASS NOTES AVAILABLE HERE?

Any students who are willing to have their notes posted publicly should email them to me as a PDF (one PDF per lecture) and include the date of the lecture. Also mention if you're willing to have your name posted with them (you may post them anonymously). I am willing to post handwritten notes provided they are neat, legible, and scanned/photographed well. In particular, your notes do not have to be typed, but if they are typed it must be with LaTeX and your notation must agree with the notation of my notes (\mathcal{T} for a topology, etc.).
