Abstract
In Abelian subalgebras of observables it is shown that the integral representations of states in terms of coherent states result from the indistinguishability of the quanta of the harmonic oscillator under consideration. It is argued that these integral representations contain a quantum de Finetti theorem on Bose-Fock space.
