The characteristic-zero comparison conjecture for symplectic annular Khovanov homology
The characteristic-zero comparison conjecture for symplectic annular Khovanov homology
Let be an annular link, let be its winding grading, and let be a field of characteristic zero. Denote by the symplectic annular Khovanov homology in absolute homological grading , and by the combinatorial annular Khovanov homology in homological grading , quantum grading , and winding grading . The characteristic-zero comparison conjecture. There is an isomorphism
If is equipped with a relative quantum equivariant grading from a non-commutative vector field, this isomorphism may be upgraded to an isomorphism of relatively trigraded groups. The claim is presented as an expected relationship, analogous to the non-annular comparison of Abouzaid and Smith, and the stronger trigraded refinement depends on the additional equivariant grading.
