Stabilization conjecture for cable links with fixed remainder

About 1 year old · traced to

Fix a knot KK, an integer nn, and a remainder rr, and consider the cable links Kn,mn+rK_{n,mn+r} as mm varies. Let s~\widetilde{\mathbf{s}} be the normalized Alexander degree preserved by the connecting maps

ϕ0:H ⁣F ⁣Lstab(Kn,mn+r;s~)→H ⁣F ⁣Lstab(Kn,(m+1)n+r;s~).\phi_0:\mathcal{H\!F\! L}^{\mathrm{stab}}\left(K_{n,mn+r};\widetilde{\mathbf{s}}\right)\to \mathcal{H\!F\! L}^{\mathrm{stab}}\left(K_{n,(m+1)n+r};\widetilde{\mathbf{s}}\right).

Cable stabilization conjecture. For a given normalized Alexander degree s~\widetilde{\mathbf{s}}, the dimension of H ⁣F ⁣Lstab(Kn,mn+r,s~)\mathcal{H\!F\! L}^{\mathrm{stab}}(K_{n,mn+r},\widetilde{\mathbf{s}}) stabilizes for sufficiently large mm, and the maps ϕ0\phi_0 are isomorphisms for sufficiently large mm. This would imply that the colimit of the directed system for the cable family with fixed remainder rr is well defined.
