摘要

In this paper we pursue the refined global Gross-Prasad conjecture for Bessel periods formulated by Yifeng Liu in the case of special Bessel periods for SO(2n + 1) x SO(2). Recall that a Bessel period for SO(2n + 1) x SO(2) is called special when the representation of SO(2) is trivial. Let pi be an irreducible cuspidal tempered automorphic representation of a special orthogonal group of an odd-dimensional quadratic space over a totally real number field F whose local component pi(v) at any archimedean place v of F is a discrete series representation. Let E be a quadratic extension of F and suppose that the special Bessel period corresponding to E does not vanish identically on pi. Then we prove the Ichino-Ikeda type explicit formula conjectured by Liu for the central value L(1/2, pi)/L(1/2, pi x chi(E)), where chi(E) denotes the quadratic character corresponding to E. Our result yields a proof of Bocherer's conjecture on holomorphic Siegel cusp forms of degree two which are Hecke eigenforms.
