Description

We will present a conjecture relating the affine Hecke category (an algebraic incarnation of annular braids) to coherent sheaves on the commuting variety. Joint work with Eugene Gorsky. This is an affine version of the conjecture (now a theorem) we proposed with Jacob Rasmussen that relates Khovanov homology to coherent sheaves on Hilbert schemes.
