On more general Gibbons-Hawking-York boundary terms for f(R) gravity
Federico Scali, Sergio Luigi Cacciatori, Matteo Galaverni +1
More general boundary conditions are introduced - with respect to known literature - which produce a well-posed stationary action principle in gravity. These conditions enco…
Aspects of Geometrodynamics in the Jordan and Einstein Frames
Gabriele Gionti, S. J.
We will summarize recent results on the Hamiltonian equivalence between the Jordan and Einstein frames based on the analysis of Brans-Dicke theory for both cases ω\neq -\frac{3}{2}…
Spherically Symmetric Geometrodynamics in Jordan and Einstein frames
Matteo Galaverni, Gabriele Gionti
Spherically symmetric geometrodynamics is studied for scalar-tensor theory and Einstein General Relativity minimally coupled to a scalar field. We discussed the importance of bound…
On the canonical equivalence between Jordan and Einstein frames
Gabriele Gionti S. J., Matteo Galaverni
A longstanding issue is the classical equivalence between the Jordan and the Einstein frames, which is considered just a field redefinition of the metric tensor and the scalar fiel…
Jordan and Einstein frames Hamiltonian analysis for FLRW Brans-Dicke theory
Matteo Galaverni, Gabriele Gionti, S. J.
We analyze Hamiltonian equivalence between Jordan and Einstein frames considering a mini-superspace model of flat Friedmann-Lemaitre-Robertson-Walker (FLRW) Universe in Brans-Dicke…
Scattering of uncharged particles in the field of two extremely charged black holes
Donato Bini, Andrea Geralico, Gabriele Gionti +2
We investigate the motion of uncharged particles scattered by a binary system consisting of extremely charged black holes in equilibrium as described by the Majumdar-Papapetrou sol…
