Resurgence and radial-limit conjecture for Habiro elements of knots
Let be a knot. Let be the formal expansion of the Habiro element around a root of unity, let denote the Borel transform of , and let denote its median Borel sum. Write when and agree up to a prefactor depending on . Resurgence and radial-limit conjecture. For every knot , (1) has a resurgent Borel transform ; (2) is analytic on and has radial limits at the points of its natural boundary; and (3), if (2) holds, then for every ,
satisfies
This is the main conjecture attributed in the source to the cited work, within a broader program concerning analytic continuation of knot invariants arising from Chern–Simons theory. The supplied material gives no evidence that it has been resolved.
