Abstract

We consider spectral decomposition of the harmonic oscillator in Rn\mathbb R^n in terms of two different orthonormal bases in L2(Rn)L^2(\mathbb R^n) consisting of its eigenfunctions. Then, using purely functional analysis tools we provide simple proofs of rotational symmetry of the Hermite projection operators studied by Kochneff, and Thangavelu's Hecke-Bochner type identity.
