## Idea

The Stone–von Neumann theorem (due to Marshall Stone and John von Neumann) says that there is – up to isomorphism – a unique irreducible unitary representation of the Heisenberg group on finitely many generators (equivalently: of the algebra of canonical commutation relations).

The analogous statement does not hold for infinitely many generators. See also Haag's theorem.
