Partial Observables in Extended Systems
Frank Hellmann
We consider "unphysical", kinematic observables that do not commute with the constraints of a gauge system in the context of an extension of the system. We show that these observab…

Multiple-event probability in general-relativistic quantum mechanics
Frank Hellmann, Mauricio Mondragon, Alejandro Perez +1
We discuss the definition of quantum probability in the context of "timeless" general--relativistic quantum mechanics. In particular, we study the probability of sequences of event…
