摘要：
Observables of a physical system identified with convex mappings sending states into probability measures. The properties of these mappings determine the spectral properties of the observables. The mutually exclusive cases of injective and surjective mappings are characterized, and the convex structure of their ranges are investigated. In particular, the validity of the Krein-Milman property for these convex sets is studied.
