MAS435/MAS6370 Algebraic Topology
Lecturer: Neil Strickland

Module information

The syllabus, timetable and assessment arrangements are here.


Lectures will happen on Mondays at 2 (room F35) and Tuesdays at 4 (Lecture Theatre 4).

Lecture notes

PDF download HTML version

Both versions of the notes contain links to various interactive demonstrations (described below) and videos.

The HTML version is new. It should be better than the PDF for viewing on a phone, or for reading with a screen reader. I would welcome any comments on either of these use cases.

There is also a separate survey of examples mentioned in the course.

I strongly recommend that you should attend lectures in person if possible. If you cannot do that, I recommend that you work from the notes and embedded videos and demonstrations. There is also a lecture progress page where you can see which sections of the notes have been covered in lectures.

Interactive demonstrations

There is a set of interactive demonstrations explaining many of the ideas in the course. I will talk through these in lectures, there are attached YouTube videos, and you can try them yourself at other times. These are experimental and under development. I welcome comments about the extent to which they are comprehensible, useful or interesting.


There will be eight homework assignments in each semester. The best five in each semester will each count for 2% of the overall course grade, making 20% in total. The remaining 80% will be based on a final exam. This will be a 2.5 hour formal closed book exam with five questions of equal value, of which you will be asked to complete four.

Weekly problems

These will appear here as the course progresses. Work should be submitted via Blackboard.

Past exam papers

The 2019-20 and 2020-21 exams were online and open book. For 2021-22 we will revert to having a closed book exam in the exam hall.


Office hours

Official office hours are 12:00-13:00 on Fridays. I will expect people to come to my office (Hicks J26) by default, but you can email me to arrange an online meeting if you prefer. If you find me in my office at some other time, then I may well be able to talk to you, but I do not guarantee it.
