Irreducibility of q-difference operators and the knot 7_4

Stavros Garoufalidis, Christoph Koutschan

Our goal is to compute the minimal-order recurrence of the colored Jones polynomial of the 7_4 knot, as well as for the first four double twist knots. As a corollary, we verify the…

Twisting q-holonomic sequences by complex roots of unity

Stavros Garoufalidis, Christoph Koutschan

A sequence fn​(q) is q-holonomic if it satisfies a nontrivial linear recurrence with coefficients polynomials in q and qn. Our main theorems state that q-holonomicity is…

The non-commutative A-polynomial of (-2,3,n) pretzel knots

Stavros Garoufalidis, Christoph Koutschan

We study q-holonomic sequences that arise as the colored Jones polynomial of knots in 3-space. The minimal-order recurrence for such a sequence is called the (non-commutative) A-po…

The SL_3 Jones polynomial of the trefoil: a case study of q-holonomic sequences

Stavros Garoufalidis, Christoph Koutschan

The SL_3 colored Jones polynomial of the trefoil knot is a q-holonomic sequence of two variables with natural origin, namely quantum topology. The paper presents an explicit set…
