| Jul 6, 2020 at 12:21 | comment | added | Nik Weaver | "Why are we allowed to identify operators constructed by these two techniques?" The short answer is: the spectral theorem. | |
| Jul 6, 2020 at 11:54 | comment | added | Paul Siegel | For me these two methods are the same: the spectral theorem asserts that self adjoint operators are unitarily equivalent to multiplication operators, and this allows us to define an action of a suitable algebra of functions i.e. a functional calculus. Did you have something else in mind? | |
