Gradings on the Hecke category, and categorification with unequal parameters

Jonas Antor, Ben Elias

We classify gradings on the Hecke category that refine the standard integer grading. We also classify object-preserving autoequivalences of the Hecke category. We obtain a natural…

An exotic Springer correspondence for $F_{4}$

Jonas Antor

We investigate the structure of the `exotic nilcone' of $F_{4}$ which is defined by exploiting certain characteristic two phenomena. We show that there are finitely many orbits on th…

Geometric realizations of affine Hecke algebras with unequal parameters

Jonas Antor

We give a $K$ -theoretic realization of all affine Hecke algebras with two unequal parameters including exceptional types. This extends the celebrated work of Kazhdan and Lusztig, w…
