Abstract

This article proves a formula relating the multiplicity of an induced representation and that of the inducing datum for the Bessel and the Fourier-Jacobi models over Archimedean local fields by generalizing the approach of C. Moeglin and J.-L. Waldspurger in [MW12], which was successful for Bessel models of special orthogonal groups over non-Archimedean local fields. As an application, we give a uniform proof of the local Gan-Gross-Prasad conjecture for all classical groups over Archimedean local fields for generic local L-parameters based on the tempered basic cases.
