The Shimura–Waldspurger correspondence for Mp2n

Abstract

We generalize the Shimura–Waldspurger correspondence, which describes the generic part of the automorphic discrete spectrum of the metaplectic group Mp2, to the metaplectic group Mp2n of higher rank. To establish this, we transport Arthur’s endoscopic classification of representations of the odd special orthogonal group SO2r+1 with r2n by using a result of J.-S. Li on global theta lifts in the stable range.
