Towards a categorification of a projection from the affine to the finite Hecke algebra in type A
Abstract:

Work of Bezrukavnikov on local geometric Langlands correspondence and works of Gorsky, NeguĊ£, Rasmussen and Oblomkov, Rozansky on knot homology and matrix factorizations suggest that there should be a categorical version of a certain natural homomorphism from the affine Hecke algebra to the finite Hecke algebra in type A, sending basis lattice elements on the affine side to Jucys-Murphy elements on the finite side. I will try to explain some of the structures involved and will talk about recent progress towards a construction of such a categorification in the setting of Hecke categories.
