The AJ conjecture for knots

The AJ conjecture was proposed in the mathematics literature by S. Garoufalidis and in the physics literature by S. Gukov about 10 years ago. It predicts a strong connection between two important knot invariants derived from very different background, namely the colored Jones function (a quantum invariant) and the A-polynomial (a geometric invariant). The colored Jones function is a sequence of Laurent polynomials which is known to satisfy a linear q-difference equation. The AJ conjecture states that by writing the linear q-difference equation into an operator form and setting q=1, one gets the A-polynomial. In this talk, I will discuss my joint work with T. Le on a geometric approach to the AJ conjecture which leads to the verification of the conjecture for many classes of knots.
