Geometric constant term functor(s)
V. Drinfeld, D. Gaitsgory
We study the Eisenstein series and constant term functors in the framework of geometric theory of automorphic functions. Our main result says that for a parabolic P in G with Levi…
On a theorem of Braden
Vladimir Drinfeld, Dennis Gaitsgory
We give a new proof of Braden's theorem ([Br]) about \emph{hyperbolic restrictions} of constructible sheaves/D-modules. The main geometric ingredient in the proof is a 1-parameter…
On algebraic spaces with an action of G_m
Vladimir Drinfeld
Let Z be an algebraic space of finite type over a field, equipped with an action of the multiplicative group . In this situation we define and study a certain algebraic space…
Fourier transform of algebraic measures
Vladimir Drinfeld
These are notes of a talk based on the work arXiv:1212.3630 joint with A. Aizenbud. Let V be a finite-dimensional vector space over a local field F of characteristic 0. Let f be a…
On the Langlands retraction
Vladimir Drinfeld
Given a root system in a vector space V, Robert Langlands defined in 1973 a canonical retraction of V onto the dominant chamber. In this note we give a short review of the material…
