Trilinear forms for representations of and local -factors
Nous montrons dans le cas simple du groupe linéaire général, comment on peut déduire de [V. Heiermann 2004] des informations précises sur le degré formel d’une représentation de carré intégrable d’un groupe -adique.
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...
