abstract

We put a new spin on Khovanov--Rozansky homology. That is, we equip $\Lambda^n$-colored $\mathfrak{sl}_{2n}$ Khovanov--Rozansky homology with an involution whose $\pm 1$-eigenspaces are link invariants. When $n=1,2,3$ (and assuming technical conjectures for $n \geq 4$), we prove that this refined invariant categorifies the spin-colored $\mathfrak{so}_{2n+1}$ quantum link polynomial. Along the way, we partially develop the theory of quantum $\mathfrak{so}_{2n+1}$ webs and make contact with $\iota$quantum groups.

    Type B webs give a complete diagrammatic presentation of the subcategory of U_q(so_{2n+1})-representations generated by the fundamental representations.

  2. Cyclic Sieving for Staircase Plane Partitions via Crystals and Electrical Networks

    math.CO 2026-07 conditional novelty 4.0 of 10

    Height-two staircase plane partitions satisfy cyclic sieving for promotion, proved by mapping promotion to rotation of 3-noncrossing perfect matchings via crystals and the electrical-network bush basis.
