(see course description above for the enrolment key)

lecture notes
The actual notes for this course begin with Chapter 27, on page 175. This file will be updated at least once a week during the semester; the current version contains everything up to the lecture from 5.11.2024 (singular homology). You may want to press the reload button to make sure you are seeing the current version.
What appears before Chapter 27 is a complete set of notes that I wrote for Topology I in a previous semester; this is convenient to have there so that I can occasionally refer to it in the current course. If you did not take my Topology I course, you will likely find that most of what is there nonetheless corresponds closely to something that you have seen in your previous topology course.
