The tilting property of Whittaker averaged central sheaves
Jeremy Taylor
We characterize the kernel of Iwahori-Whittaker averaging in microlocal terms. Applying this to automorphic sheaves, we generalize Faergeman and Raskin's theorem that anti-tempered…

Universal monodromic tilting sheaves
Jeremy Taylor
We construct the universal monodromic big tilting sheaf on base affine space and calculate its endomorphisms. By formal completion, we recover Soergel's pro-unipotent Endomorphisme…
