The L-function of some Siegel modular
3-folds and endoscopic lifts
Exposé de Takuya Yamauchi
(Toronto)
In this talk, we rst discuss about a conjectural description of the L-function of Siegel modular 3-folds S and then next study
the non-contribution or contribution of endoscopic lifts to the middle
cohomology of some specic S . An explicit example which is related
to Klein cubic 3-fold will be given. This is a joint work with Takeo
Okazaki.
