Witryna$\begingroup$ @tomasz Not all self-adjoint operators have eigenbases (only the ones either compact or with compact resolvent); but they have an associated spectral decomposition. And the property of "commuting" for unbounded self-adjoint operators is slightly more complicated than the usual $[A,B]=0$ (you need to check that the …
