The Rest-Frame Instant Form of Dynamics and Dirac's Observables
Luca Lusanna
Talk given at the International Workshop ``Physical Variables in Gauge Theories", Dubna 1999
Tetrad Gravity: III) Asymptotic Poincare' Charges, the Physical Hamiltonian and Void Spacetimes
Luca Lusanna, Roberto de Pietri
A discussion of asymptotic weak and strong Poincare' charges in metric gravity is given to identify the proper Hamiltonian boundary conditions. The asymptotic part of the lapse and…
Towards a unified description of the four interactions in terms of Dirac-Bergmann observables
Luca Lusanna
A review is given of the status and developments of the research program aiming to reformulate the physics of the four interactions at the classical level in a unified way in terms…
A Canonical Decomposition in Collective and Relative Variables of a Klein-Gordon Field in the Rest-Frame Wigner-Covariant Instant Form
L. Lusanna, M. Materassi
The canonical decomposition of a real Klein-Gordon field in collective and relative variables proposed by Longhi and Materassi is reformulated on spacelike hypersurfaces. This allo…
