Relative trace formulae toward Bessel and Fourier–Jacobi periods on unitary groups

چکیده
We propose an approach, via relative trace formulae, toward the global restriction problem involvingBessel or Fourier–Jacobi periods on unitary groupsUn×Um , generalizing the work of Jacquet–Rallis form = n−1 (which is a Bessel period). In particular, whenm = 0, we recover a relative trace formula proposed by Flicker concerning Kloosterman/Fourier integrals on quasi-split unitary groups.As evidences for our approach,we prove the vanishing part of the fundamental lemmas in all cases, and the full lemma for Un × Un .

Fourier–jacobi Periods and the Central Value of Rankin–selberg L-functions
1.1. The refined Gan–Gross–Prasad conjecture. In this paper, as a sequel of [Xue14], we formulate a refinement to the global Gan–Gross–Prasad conjecture for the Fourier–Jacobi periods on U(n) × U(n) and prove it under some local conditions, assuming some expected properties of the L-packets and some parts of the local Gan–Gross–Prasad conjecture. This refinement is modeled on some recent work o...
متن کاملOn the Scaling Limits of Determinantal Point Processes with Kernels Induced by Sturm–Liouville Operators
By applying an idea of Borodin and Olshanski [J. Algebra 313 (2007), 40–60], we study various scaling limits of determinantal point processes with trace class projection kernels given by spectral projections of selfadjoint Sturm–Liouville operators. Instead of studying the convergence of the kernels as functions, the method directly addresses the strong convergence of the induced integral opera...
متن کاملFourier - Jacobi Expansion of Eisenstein Series on Unitary Groups of Degree Three
After reformulating Shintani’s theory of FourierJacobi expansion of automorphic forms on U(2, 1) in the adelic setting, we show that the primitive components of holomorphic Eisenstein series are expressed in terms of the periods of primitive theta functions and critical values of Hecke L-functions.
متن کاملON THE q - BESSEL FOURIER TRANSFORM ( COMMUNICATED BY R . K RAINA )
In this work, we are interested by the q-Bessel Fourier transform with a new approach. Many important results of this q-integral transform are proved with a new constructive demonstrations and we establish in particular the associated q-Fourier-Neumen expansion which involves the q-little Jacobi polynomials.
