Simultaneity, radar 4-coordinates and the 3+1 point of view about accelerated observers in special relativity
D. Alba, L. Lusanna
After a review of the 1+3 point of view on non-inertial observers and of the problems of rotating reference frames, we underline that was is lacking in their treatment is a good gl…
From Einstein's Hole Argument to Dirac and Bergmann Observables
Luca Lusanna
The individuation of point-events and the Hamiltonian way of distinguishing gravitational from inertial effects in general relativity are discussed.
Background-Independent Gravitational Waves
Juri Agresti, Roberto De Pietri, Luca Lusanna +1
A Hamiltonian linearization of the rest-frame instant form of tetrad gravity (gr-qc/0302084), where the Hamiltonian is the weak ADM energy , in a completely fixed (…
Hamiltonian linearization of the rest-frame instant form of tetrad gravity in a completely fixed 3-orthogonal gauge: a radiation gauge for background-independent gravitational waves in a post-Minkowskian Einstein spacetime
Juri Agresti, Roberto De Pietri, Luca Lusanna +1
In the framework of the rest-frame instant form of tetrad gravity, where the Hamiltonian is the weak ADM energy , we define a special completely fixed 3-orthogonal…
General Covariance and the Objectivity of Space-Time Point-Events: The Physical Role of Gravitational and Gauge Degrees of Freedom in General Relativity
Luca Lusanna, Massimo Pauri
(Abridged Abstract) This paper deals with a number of technical achievements that are instrumental for a dis-solution of the so-called {\it Hole Argument} in general relativity. Th…
