Recall that the GNS theorem allows us to take any C*-algebra of observables A and, having chosen some state ω, represent it via the representation πω as a subalgebra πω (A) ⊆ B(Hω ) for some Hilbert space Hω . Using the weak operator topology on B(Hω ) as a physically relevant notion of approx ...

Phase Space Approach to Solving the Time

The “complete” vN basis, where n and l run over all integers, spans the infinite Hilbert space. In any numerical calculation, however, n and l take ...
