Hoste–Przytycki wrapping number conjecture for annular links

Let AA be the annulus, and let LA×IL\subset A\times I be an annular link. Let wrap(L)\mathrm{wrap}(L) be the minimal geometric intersection number between LL and a meridional disk in A×IA\times I. Let KBSM(A)\mathrm{KBSM}(A) denote the Kauffman bracket skein module of the annulus, equipped with its annular degree. Wrapping Number Conjecture. The Kauffman bracket skein module of an annular link LL is nonzero in annular degree wrap(L)\mathrm{wrap}(L). This conjecture is the skein-theoretic predecessor motivating Grigsby's categorified version. It was posed by Hoste and Przytycki in 1995, and the source presents it as an older open conjecture.
