Derived Weil Representation and Relative Langlands Duality

Representation Theory 2026-03-30 v1

Abstract

The Weil representation is a particularly significant linear representation of the metaplectic group, used in the study of theta correspondence. In this paper, I introduce a derived category version of the Weil representation in the local field case. For the dual pair (GLn,GLm) (\mathrm{GL}_n,\mathrm{GL}_m) , I give a coherent description of this category, in the philosophy of relative Langlands duality.
