The spectral gluing theorem revisited

Algebraic Geometry 2024-04-17 v4 Representation Theory

Abstract

We strengthen the gluing theorem occurring on the spectral side of the geometric Langlands conjecture. While the latter embeds IndCohN(LSG)IndCoh_N(LS_G) into a category glued out of 'Fourier coefficients' parametrized by standard parabolics, our refinement explicitly identifies the essential image of such embedding.
