Non-vanishing of geometric Whittaker coefficients for reductive groups
Joakim Faergeman, Sam Raskin
We prove that cuspidal automorphic D-modules have non-vanishing Whittaker coefficients, generalizing known results in the geometric Langlands program from GL_n to general reductive…
Affine Beilinson-Bernstein localization at the critical level
David Yang, Sam Raskin
We prove the Frenkel-Gaitsgory localization conjecture describing regular Kac-Moody representations at critical level via eigensheaves on the affine Grassmannian using categorical…
Coulomb branches of noncotangent type (with appendices by Gurbir Dhillon and Theo Johnson-Freyd)
Alexander Braverman, Gurbir Dhillon, Michael Finkelberg +2
We propose a construction of the Coulomb branch of a gauge theory corresponding to a choice of a connected reductive group and a symplectic finite-dimensio…
The Arinkin-Gaitsgory temperedness conjecture
Joakim Faergeman, Sam Raskin
Arinkin and Gaitsgory defined a category of tempered D-modules on Bun_G that is conjecturally equivalent to the category of quasi-coherent (not ind-coherent!) sheaves on LocSys_{\c…
Tate's thesis in the de Rham Setting
Justin Hilburn, Sam Raskin
We calculate the category of D-modules on the loop space of the affine line in coherent terms. Specifically, we find that this category is derived equivalent to the category of ind…
Exceptional loci in Lefschetz theory
Sam Raskin, Geoffrey Smith
Let be a morphism of varieties. Given a hyperplane in , there is a Gysin map from the compactly supported cohomology of …
