Lifting automorphic representations on the double covers of orthogonal groups
Suppose that and are connected reductive groups over a number field and that an -homomorphism is given. The Langlands functoriality conjecture predicts the existence of a map from the automorphic representations of to those of . If the adelic points of the algebraic groups , are replaced by their metaplectic covers, one may hope to specify an analogue of the -group (depending on the cover), and then one may hope to construct an analogous correspondence. In this article, we construct such a correspondence for the double cover of the split special orthogonal groups, raising the genuine automorphic representations of to those of . To do so, we use as integral kernel the theta representation on odd orthogonal groups constructed by the authors in a previous article . In contrast to the classical theta correspondence, this representation is not minimal in the sense of corresponding to a minimal coadjoint orbit, but it does enjoy a smallness property in the sense that most conjugacy classes of Fourier coefficients vanish
