Algebra-action generation conjecture for stable torus-knot homology

About 16 years old · traced to

Let An,m\mathcal{A}_{n,m} be algebras represented on the stable homology space H(Tn,m)\mathcal{H}(T_{n,m}), and let e1,…,ene_1,\ldots,e_n denote the even polynomial generators and ξ1,…,ξm−1\xi_1,\ldots,\xi_{m-1} the odd generators. Algebra-action generation conjecture. There exists a sequence of algebras An,m\mathcal{A}_{n,m} such that: (1) their action commutes with multiplication by polynomials in e1,…,ene_1,\ldots,e_n; (2) for every kk with ∣k∣<n|k|<n, the differential dkd_k belongs to An,m\mathcal{A}_{n,m}; (3) H(Tn,m)\mathcal{H}(T_{n,m}) is generated by its top level under the action of An,m\mathcal{A}_{n,m}; and (4) the top level for the (m,m+n)(m,m+n) torus knot coincides with the zero level of the homology of the (m,n)(m,n) torus knot multiplied by the volume form ξ1ξ2⋯ξm−1\xi_1\xi_2\cdots\xi_{m-1}. This conjecture proposes an algebraic mechanism generating stable torus-knot homology and relating top and zero levels under the stated torus-knot transformation; the source does not give a resolution status.
