4. Hilbert schemes


    1. Add remark

      Problem 4.1.

      Fixing a slope, what corresponds to a stable basis in K-theory of Hilbert schemes in the cocenter of the Hecke algebra?


        • Add remark

          Problem 4.2.

          Compute endomorphism algebra (in the homotopy category) of projectors, and relate it to coordinate ring and of charts on Hilb^n(\mathbb{C}^2)


            • Add remark

              Problem 4.3.

              Relate tr(T(m,n)) to rings of quasi-invariants and to A. Wilson’s conjecture. Describe H^*(\text{Hilb}(x^{nd}=y^n)) as a module over rational Double Affine Hecke algebra (DAHA) and relate it to the above.

                •     We define Hilb^n(x^2=0)=\{\text{codiminsional }n \text{ ideals in }\mathbb{C}[x,y]/(x^2=0)\}\subseteq Hilb^n(\mathbb{C}^2)

                  Problem 4.4.

                  Relate Hilb^n(x^2=0) to HH of the arc algebra.

                      Problem 4.5.

                      Let \mathcal{F}(\beta) be the sheaf on Hilb^n(\mathbb{C}^2) associated to \beta. How does \mathcal{F}(\beta)|_{\text{Hilb}^n(x^2=0)} relate to Khovanov homology of \beta?


                        • Add remark

                          Problem 4.6.

                          Construct link invariants for links in lens spaces using Hilb([\mathbb{C}^2/(\mathbb{Z}/l\mathbb{Z}]) and relate to wreath Macdonald polynomials.
