Travaux de Frenkel, Gaitsgory et Vilonen sur la correspondance de Drinfeld-Langlands
The theory of Whittaker functors for is an essential technical tools in Gaitsgory’s proof of the Vanishing Conjecture appearing in the geometric Langlands correspondence. We define Whittaker functors for and study their properties. These functors correspond to the maximal parabolic subgroup of , whose unipotent radical is not commutative.We also study similar functors corresponding to the Siegel parabolic subgroup of , they are related with Bessel models for and Waldspurger models for .We...
