Stability issues of nonlocal gravity during primordial inflation
Enis Belgacem, Giulia Cusin, Stefano Foffa +2
We study the cosmological evolution of some nonlocal gravity models, when the initial conditions are set during a phase of primordial inflation. We examine in particular three mode…
Conformal symmetry and nonlinear extensions of nonlocal gravity
Giulia Cusin, Stefano Foffa, Michele Maggiore +1
We study two nonlinear extensions of the nonlocal gravity theory. We extend this theory in two different ways suggested by conformal symmetry, either replacing $\Bo…
Non-local gravity with a Weyl-square term
Giulia Cusin, Stefano Foffa, Michele Maggiore +1
Recent work has shown that modifications of General Relativity based on the addition to the action of a non-local term , or on the addition to the equations of motio…
Non-local gravity and dark energy
Michele Maggiore, Michele Mancarella
We discuss a nonlocal modification of gravity obtained adding a term to the Einstein-Hilbert action. We find that the mass parameter only affects the non-ra…
