Knot theory

introduction

• three Reidemeister moves

 

 

examples

• trivial knot
• Hopf link
• figure 8 knot
• trefoil knot

 

 

knot diagram

• projection to two dimensional space

 

 

 

 

knot invariants

• Alexander-Conway polynomial
• Jones polynomial
• Vassiliev invariants
• define them recursively using the skein relation
• Reidemeister's theorem is used to prove that they are knot invariants
• The puzzle on the mathematical side was that these objects are invariants of a three dimensional situation, but one did not have an intrinsically three dimensional definition.
• There were many elegant definitions of the knot polynomials, but they all involved looking in some way at a two dimensional projection or slicing of the knot, giving a two dimensional algorithm for computation, and proving that the result is independent of the chosen projection.
• This is analogous to studying a physical theory that is in fact relativistic but in which one does not know of a manifestly relativistic formulation - like quantum electrodynamics in the 1930's.

 

 

Jones polynomial

• Kauffman bracket
• Hecke algebra

 

 

Knot theory, statistical mechanics and quantum groups

• Jones polynomial and \(U_q[\mathfrak{sl}(2)]\)
  
• Knot Theory and Statistical Mechanics

• using the Boltzmann weights from the various exactly solvable models, we can discover an infinite series of invariants of knots
• so the problem is to find a nice set of Boltzmann weights which give non-trivial invariants
