Lecture Notes in Loop Quantum Gravity. LN4: Hamiltonian framework
Lorenzo Fatibene, Marco Ferraris, Andrea Orizzonte
We discuss a covariant setting for Hamiltonian formalism in a relativistic field theory and we use this to obtain again the properties of Hamilton principal functional in Newtonian…
A variational framework for higher order perturbations
F. Chiaffredo, L. Fatibene, M. Ferraris +2
A covariant, global, variational framework for perturbations in field theories is presented. Perturbations are obtained as vertical vector fields on the configuration bundle and th…
Hubble drift in Palatini -theories
L. Del Vecchio, L. Fatibene, S. Capozziello +3
In a Palatini -model, we define chonodynamical effects due to the choice of atomic clocks as standard reference clocks and we develop a formalism able to quantitati…
Extended Cosmology in Palatini f(R)-theories
Paolo Pinto, Leonardo Del Vecchio, Lorenzo Fatibene +1
We consider the cosmological models based on Palatini f(R)-theory for the function f(R)=aR-2bR^2-3c/R, which, when only dust visible matter is considered, is called dune cosmology…
Discrete Relativistic Positioning Systems
Sante Carloni, Lorenzo Fatibene, Marco Ferraris +2
We discuss the design for a discrete, immediate, simple relativistic positioning system (rPS) which is potentially able of self-positioning (up to isometries) and operating without…
Constraining the Physical State by Symmetries
L. Fatibene, M. Ferraris, G. Magnano
After reviewing the hole argument and its relations with initial value problem and general covariance, we shall discuss how much freedom one has to define the physical state of a s…
