Polynomial affine model of gravity in three-dimensions
Oscar Castillo-Felisola, Bastian Grez, Oscar Orellana +4
In this work, we explore a three-dimensional formulation of the polynomial affine model of gravity, which is a model that extends general relativity by relaxing the equivalence pri…
Aspects of the polynomial affine model of gravity in three dimensions
Oscar Castillo-Felisola, Oscar Orellana, José Perdiguero +3
The polynomial affine gravity is a model that is built up without the explicit use of a metric tensor field. In this article we reformulate the three-dimensional model and, given t…
Emergent metric and geodesic analysis in cosmological solutions of (torsion-free) Polynomial Affine Gravity
Oscar Castillo-Felisola, Jose Perdiguero, Oscar Orellana +1
Starting from an affinely connected space, we consider a model of gravity whose fundamental field is the connection. We build up the action using as sole premise the invariance und…
Kaluza-Klein theory in the limit of large number of extra dimensions
Fabrizio Canfora, Alex Giacomini, Alfonso R. Zerwekh
The Kaluza-Klein compactification in the limit of large number of extra dimensions is studied. Starting point is the Einstein-Hilbert action plus cosmological constant in 4+D dimen…
