I'll let you in on a secret: they're all abstract. But don't tell anyone. :-)martinbn said:What exactly is abstract space and (I guess) non-abstract?
It's curious how this subject tends to generate more heat than I would have expected.
No, it just means that the abstract group ##SO(3)## is being represented as operators on different vector spaces.Rotations act on space and they act on the wave functions as well. Does that make them both physical and unphysical?
