Unipotent representations and the categorical trace of Frobenius
Wyatt Reeves
We give a new proof of the classification of unipotent representations for split finite groups of Lie type. To do this, we first construct an (infinity, 2)-categorification of Lusz…

On the excursion algebra
Dennis Gaitsgory, Kevin Lin, Wyatt Reeves
The excursion algebra associated to a scheme X over a finite field and a reductive group G is the algebra of global functions on the stack of arithmetic G-local systems on X. When…

Coherent sheaves, sheared D-modules, and Hochschild cochains
Dario Beraldo, Kevin Lin, Wyatt Reeves
We show that the category of ind-coherent sheaves on a quasi-smooth scheme is naturally tensored over the category of sheared D-modules on its shifted cotangent bundle, commuting w…
