WebOct 7, 2024 · The central message is that the Hilbert space itself tells us almost nothing about a theory. The pattern of observables is what matters. Different ways of representing the Hilbert space may be more or less convenient for different patterns of observables, but the observables are what matters. Yes, there are many different fermionic field theories.

The background in the physics of vibrations has been explained in this way: Spectral theory is connected with the investigation of localized vibrations of a variety of different objects, from atoms and molecules in chemistry to obstacles in acoustic waveguides. These vibrations have frequencies, and the issue is to decide when such localized vibrations occur, and how to go about computing the frequencies. This is a very complicated problem since every obje…
