Covariance Systems on the Projective Line
N. Pinamonti, M. Toller
We study the positive-operator-valued measures on the projective real line covariant with respect to the projective group, assuming that the energy is a positive operator. This pro…
Variance of the Quantum Coordinates of an Event
M. Toller
We study the variances of the coordinates of an event considered as quantum observables in a Poincare' covariant theory. The starting point is their description in terms of a covar…
Localization of Events in Space-Time
Marco Toller
The present paper deals with the quantum coordinates of an event in space-time, individuated by a quantum object. It is known that these observables cannot be described by self-adj…
On the Quantum Space-Time Coordinates of an Event
M. Toller
This paper gives a representation of the most general positive operator valued measure in Minkowski space-time, covariant with respect to the Poincare' group. It provides the corre…
