Endoscopy for affine Hecke categories
Yau Wing Li
We show that the neutral block of the affine monodromic Hecke category for a reductive group is monoidally equivalent to the neutral block of the affine Hecke category for the endo…

Endoscopy for metaplectic affine Hecke categories
Gurbir Dhillon, Yau Wing Li, Zhiwei Yun +1
For a possibly twisted loop group , and any character sheaf of its Iwahori subgroup, we identify the associated affine Hecke category with a combinatorial category of Soergel b…

Matchings in Corona graph and classical symmetric varieties
Yau Wing Li
We introduce an alternative combinatorial parametrization of Borel orbits in classical symmetric varieties using matchings of the Corona graph. As an application, we obtain ultra l…
