MX4540: KNOTS (2022-2023)

Last modified: 20 Jan 2023 16:02


Course Overview

A knot is a closed curve in three dimensions.  How can we tell if two knots are the same?  How can we tell if they are different?  This course answers these questions by developing many different "invariants" of knots.  It is a pure mathematics course, drawing on simple techniques from a variety of places, but with an emphasis on examples, computations and visual reasoning.

Course Description

Knots have been studied mathematically since the 19th century, and knot theory connects with many other areas of pure maths and even theoretical physics. This course concentrates on knot invariants: numbers, polynomials or groups that try to "measure" properties of the knots. Classic invariants such as the colouring group will lead to more modern ones like the Jones polynomial, which was only discovered in the mid-1980s.

Topics will include the following:

  • Knots and links.
  • Linking number.
  • Colourings,determinants and the colouring group.
  • The Alexander polynomial.
  • The Jones polynomial.
  • The Genus.

Syllabus

  • Knots and links
  • Diagrams and Reidemeister moves
  • Sums, mirrors and reverses
  • The linking number
  • Colourability
  • The determinant
  • The colouring group
  • Alexander Polynomial
  • Jones polynomial: definition, computations, properties
  • Jones polynomial and alternating links
  • The genus of a knot and prime knots
