Quantum Color Newton Rings
Abstract
We study integral Newton rings attached to symmetric quantum colors. We show that their boundary values at a deleted node are exactly the elements of Habiro's cyclotomic completion, and we describe their quantum neighborhoods at q=1 uniformly in the rank. The symmetric-color sln invariants of a knot are the values of an element of such a ring. In its expansion at q=1, the coefficient of (q−1)m has denominator dividing the (n−1+2m)th power of the Alexander polynomial, with integral numerator, and this exponent is sharp. For 52 and 61 at q=i, the period matrices of the rank-two coefficient recurrences have spectral modules of exact order three in the Picard group of an affine elliptic curve.

AB - We study integral Newton rings attached to symmetric quantum colors. We show that their boundary values at a deleted node are exactly the elements of Habiro's cyclotomic completion, and we describe their quantum neighborhoods at q=1 uniformly in the rank. The symmetric-color sl_n invariants of a knot are the values of an element of such a ring. In its expansion at q=1, the coefficient of (q−1)^m has denominator dividing the (n−1+2m)th power of the Alexander polynomial, with integral numerator, and this exponent is sharp. For 5_2 and 6_1 at q=i, the period matrices of the rank-two coefficient recurrences have spectral modules of exact order three in the Picard group of an affine elliptic curve.
