Abstract

We report a work in progress on computing the value of characters of cell modules of Hecke category at compositions of Coxeter element. The computation gives a table of q,t-polynomials with rows and columns labeled by partitions. One of the key ingredient is the geometric realization of Hecke category and its cocenter via graded sheaves as developed in the joint work with Quoc. P. Ho.
