A two-variable series for knot complements
A two-variable series for knot complements
The physical 3d \mathcal N = 2 theory T[Y] was previously used to predict the existence of some 3 -manifold invariants \widehat{Z}_{a}(q) that take the form of power series with integer coefficients, converging in the unit disk. Their radial limits at the roots of unity should recover the Witten–Reshetikhin–Turaev invariants. …
