9. Miscellaneous


    1. Add remark

      Problem 9.1.

      What is the action of the full twist on the trace of the Hecke category? Does it relate to \nabla? How does it act on Schur objects?


        • Add remark

          Problem 9.2.

          Let B_w\in SBim_n be the indecomposable Soergel bimodule associated to w\in S_n. Compute Ext_{R-R \text{ bimod}}(B_v,B_w) and develop its diagrammatics.


            • Add remark

              Problem 9.3.

              Find functors from derived horizontal trace computing \mathcal{gl}(m|n)-homology.


                • Add remark

                  Problem 9.4.

                  Find a basis of the coinvariant ring of \mathbb{C}[x_1,\ldots,x_n,y_1,\ldots,y_n,\theta_1,\ldots,\theta_n,\phi_1,\ldots,\phi_n]
                  and a combinatorial model for the Frobenius characteristic in the \mathbb{C}[x_1,\ldots,x_n,y_1,\ldots,y_n,\theta_1,\ldots,\theta_n]
                  case, does the basis proposed by Haglund-Sergel work?


                    • Add remark

                      Problem 9.5.

                      Take P,Q\in SYT(\lambda), how do tr(P) and tr(G) relate?


                        • Add remark

                          Problem 9.6.

                          1. Relate tr(T(m,n)) to rings of quasi-invariants and to A. Wilson’s conjecture on \nabla_{p_1}^n.
                          2. Describe H^*(\text{Hilb}(x^{nd}=y^n)) as a module over rational Double Affine Hecke algebra (DAHA) and relate it to the above.


                            • Add remark

                              Problem 9.7.

                              Compare recursions for q,t-Catalan numbers C_n(q,t) with the recursions for HHH.
