MA3F2, Knot Theory
Winter 2008

Course Description

"A knot may be regarded as a continuous loop of (thin rubber) string. There are two fundamental problems: Is the loop really knotted? When is a loop got from another by continuous deformation? The problem is tackled by computing invariants. If for instance we have a computable way to assign invariant numbers to knots then two knots with different numbers can not be equivalent. Another approach is to look at the topology of the complement of the knot. Can we find a surface with the knot as boundary? What properties does it have?" (Taken from the pink booklet.)


The schedule has a list of topics, organized by lecture. Links to example sheets will be added as the term progresses. I will also try to post my lecture notes (sans pictures, unfortunately).

Reference materials

We will be closely following Professor Sanderson's lecture notes. This course has no set text. However, the books The knot book, by Colin Adams and An introduction to knot theory, by W.B. Raymond Lickorish may be useful. The MathStuff website for the course may also be useful.

Example sheets

See the schedule for the example sheets. Professor Sanderson's example sheets will also be useful. Notice that his example sheets actually have more examples than mine! The same link leads to written solutions, as well.


The exam will be closed book. I'll post the time and place on the schedule. Past exams can be found on Sanderson's website and also at Mathstuff.


There will be no assessed work for this class.


Please tell me in person, or via email, about any errors on this website or made in class. I am especially keen to hear about mathematical errors, gaffes, or typos appearing in the lecture notes.
