Abstrakt: We prove certain identities between Bessel functions attached to irreducible unitary representations ofPGL2(R) and Bessel functions attached to irreducible unitary representations of the double cover ofSL2(R). These identities give a correspondence between such representations which turns out to be the Waldspurger correspondence. In the process we prove several regularity theorems for Bessel distributions which appear in the relative trace formula. In the heart of the proof lies a classical result of Weber and Hardy on a Fourier transform of classical Bessel functions. This paper constitutes the local (real) spectral theory of the relative trace formula for the Waldspurger correspondence for which the global part was developed by Jacquet. [ABSTRACT FROM AUTHOR]
