Introduction Knots and Knot Invariants The Jones Polynomial and Generalizations Definition A knot is an embedding f : S 1 S 3. A knot is usually represented through projection into R 2 such that: At most two segments come together at any one point Whenever two segments meet we designate which arc is the over crossing and which is the under crossing. Figure: Five Knots. Are any of them the same?
Introduction Knots and Knot Invariants The Jones Polynomial and Generalizations Definition ([8]) Two knots are equivalent if there is an orientation preserving piecewise linear homeomorphism h : S 3 S 3 that maps one knot to the other. Figure: There are three different knot types in this figure. The red knots are unknots, the green knots are trefoils and the blue knot is a figure 8 knot.
Introduction Knots and Knot Invariants The Jones Polynomial and Generalizations We can use knot invariants to help us tell whether or not two knot diagrams represent equivalent knots. Definition A knot invariant is a property of a knot that does not change under ambient isotopy. If two knots have different values for any knot invariant, then it is impossible to transform one into the other, thus they are not equivalent.
Introduction Knots and Knot Invariants The Jones Polynomial and Generalizations Theorem (Reidemeister 1928) Any two equivalent knots are related by planar isotopy and a sequence of the three Reidemeister moves. Reidemeister 1: Reidemeister 2: Reidemeister 3:

Introduction Knots and Knot Invariants The Jones Polynomial and Generalizations We can adapt the Kauffman Bracket to be a knot invariant. Definition The Jones Polynomial of a knot is a knot invariant of a knot K with diagram D defined by ( ) V(K) = ( A) 3w(D) D where w(d) is the writhe of the diagram. q 1/2 =A 2 w(d) = # #
Introduction Knots and Knot Invariants The Jones Polynomial and Generalizations We can also view the Jones Polynomial as a specific case of the Reshetikhin-Turaev invariant of the knot. Consider the Lie algebra sl 2 of traceless two-by-two complex matrices. It has universal enveloping algebra U(sl 2 ), which has quantum deformation U q (sl 2 ). U q (sl 2 ) is an algebra over the ring Q(q) of rational functions in the determinant q. Given a knot diagram, we can color the diagram with an 2 dimensional representation of U q (sl 2 ) V.

Introduction Knots and Knot Invariants The Jones Polynomial and Generalizations We can think of the N dimensional colored Jones polynomials as a linear combination of the original Jones polynomial on cablings of the knots, in the same way that the N dimensional representation can be expressed as a linear combination of V2 k,k n 1. We can express this linear combination recursively as: g 1 = 1 g 2 = z g 3 = zg i 1 g i 2. For example, g 3 = z 2 1 so the 3 dimensional colored Jones polynomial is the Jones Polynomial of the two cabled figure 8 minus 1.

Head and Tail of the Colored Jones Polynomial Volume-ish Theorem In 2006, Dasbach and Lin conjectured that the head and tail exist for alternating knots. In 2011, Armond proved this for alternating links and for adequate links, using skein theoretical techniques. The head and tail do not exist for all knots, however. Armond and Dasbach showed that the head and tail does not exist for the (4,3) torus knot.
