Selecta Mathematica 24, no. 1: 227-301.1022-18241420-9020http://nrs.harvard.edu/urn-3:HUL.InstRepos:41275771We introduce the space of parameters for the metaplectic Langlands theory as factorization gerbes on the affine Grassmannian, and develop metaplectic Langlands duality in the incarnation of the metaplectic geometric Satake functor. We formulate a conjecture in the context of the global metaplectic Langlands theory, which is a metaplectic version of the “vanishing theorem” of Gaitsgory (Astérisque 370:1–112, 2015, Theorem 4.5.2).en-USJournal Article2019-08-2910.1007/s00029-017-0360-4
