A Microlocal Description of Aubert-Zelevinsky Duality on Unipotent -Parameters

Jonas Antor, Emile Okada

We give a microlocal description of the Aubert--Zelevinsky involution for all unipotent representations of all inner forms of simple adjoint unramified -adic groups. Via the rea…

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

Jonas Antor

We investigate the structure of the `exotic nilcone' of 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 -theoretic realization of all affine Hecke algebras with two unequal parameters including exceptional types. This extends the celebrated work of Kazhdan and Lusztig, w…

Canonical bases via pairing monomials

Jonas Antor

For any quantum group of finite ADE type, we prove a new formula for the standard bilinear form evaluated at monomials. Combining this with ideas from the Lusztig-Shoji algorithm,…

Formality in the Deligne-Langlands correspondence

Jonas Antor

The Deligne-Langlands correspondence parametrizes irreducible representations of the affine Hecke algebra by certain perverse sheaves. We show that this…
