3 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?
4 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.
5 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.
6 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:

10 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) = # #
11 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.

19 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.

58 Visual Representations of the Patterns The Conjectures Hyperbolic Volume of a Knot Definition The hyperbolic volume of a hyperbolic knot K is the volume of the unique hyperbolic metric on the knot complement (S 3 \K) We can calculate the hyperbolic volume of the knot by building its complement out of ideal tetrahedrons.

60 Visual Representations of the Patterns The Conjectures Hyperbolic Volume of a Knot Conjecture (Kashaev, Murakami, Marakami) The Hyperbolic Volume Conjecture states that: vol(s 3 log J N,K \K) = 2π lim (e2πi/n ) N N The hyperbolic volume conjecture has been proved for: torus knots, the figure-eight knot, Whitehead doubles of (2, p)-torus knots, positive iterated torus knots, Borromean rings, (twisted) Whitehead links, Borromean double of the figure-eight knot, Whitehead chains, and fully augmented links (see [10]).
61 Visual Representations of the Patterns The Conjectures Hyperbolic Volume of a Knot If we let m K (N) be the maximum coefficient of the Colored Jones Polynomial of a knot K, then J N,K (e2πi/n ) M m K (N) Mm K (N), n=0 where M is the number of terms in the colored Jones polynomial. For alternating knots, M = N(N 1)c/2 while for all knots the growth rate of the breadth is at most quadratic, so M a 2 N 2 +a 1 N +a 0.
62 Visual Representations of the Patterns The Conjectures Hyperbolic Volume of a Knot Thus, log J k (N)(e 2πi/N ) log(a 2 N 2 +a 1 N +a 0 )m K (N) lim lim N N N N log(a 2 N 2 +a 1 N +a 0 ) = lim N = lim N N logm K (N).

64 Head and Tail of the Colored Jones Polynomial Volume-ish Theorem Not much other work had been done studying the middle coefficients on the colored Jones polynomial but there is current work being done studying patterns and stabilization in the other coefficients. This work has also been related to the Hyperbolic Volume Conjecture. There is also work being done by Garoufalidis studying the asymptotic behavior and recurrence relations of the colored Jones polynomial for a knot.
65 Head and Tail of the Colored Jones Polynomial Volume-ish Theorem Definition The head of the Colored Jones Polynomial of a knot K - if it exists - is a polynomial whose first N terms (highest powers of q) have the same coefficients as the first N terms of J N,K. Definition The tail of the Colored Jones Polynomial of a knot K - if it exists - is a polynomial whose last N terms (lowest powers of q) have the same coefficients as the first N terms of J N,K.

67 Head and Tail of the Colored Jones Polynomial Volume-ish Theorem The Head of the Colored Jones Polynomial of 4 1 J N,4 1 (q) = = = N 1 n=0 k=1 N 1 n=0 k=1 N 1 n n=0 k=1 n {N k}{n +k} n (a N k a N+k )(a N+k a N k ) q N q k q k +q N The max degree of each summand is Nn so decreasing the n by 1 changes the max degree by N thus only n = N 1 contributes to the head and tail.
68 Head and Tail of the Colored Jones Polynomial Volume-ish Theorem J N,4 1 (q) = reindex:k = N k N 1 N 1 HT = n=0 k=1 k=1 N 1 HT = k=1 N 1 = q N N 1 HT = k =1 n q N q k q k +q N q N q k q k +q N q N q k k=1 1 q k N (1 q k )
69 Head and Tail of the Colored Jones Polynomial Volume-ish Theorem J N,4 1 (q) HT = N 1 k =1 (1 q k ) Theorem (Euler s Pentagonal Number Theorem) (1 x n ) = ( 1) k x k(3k 1)/2 n=1 k= = 1 x x 2 +x 5 +x 7 x 12 x 15 + A similar arguments shows that the head of twists knots is the same polynomial.
70 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.
71 Head and Tail of the Colored Jones Polynomial Volume-ish Theorem The tails are known for the following knots: All knots up to 7 crossing (2,p) torus knots twist knots generalized twist knots 2-bridge knots
72 Head and Tail of the Colored Jones Polynomial Volume-ish Theorem What does the head and the tail tell us about the geometry of the knot? Theorem (Dasbach, Lin) Volume-ish Theorem: For an alternating, prime, non-torus knot K let J K,2 (q) = a n q n + +a m q m be the Jones polynomial of K. Then 2v 0 (max( a m 1, a n+1 ) 1) Vol(S 3 K) Vol(S 3 K) 10v 0 ( a n+1 + a m 1 1). Here, v is the volume of and ideal regular hyperbolic tetrahedron.
73 Conjectures and Questions Head and Tail of the Colored Jones Polynomial Volume-ish Theorem 1 The coefficients of J N,K are periodic with period N, especially for the middle terms as N gets large. 2 There is a sinusoidal oscillation in the first and last quarter of the coefficients (but after the head and the tail). 3 The growth rate of the max coefficient is exponential and related to the hyperbolic volume of the knot. 4 How much does head and tail of the colored Jones polynomial tell us about the knot? 5 How much do the middle coefficients tell us?
