A polynomial affine model of gravity: after ten years
Oscar Castillo-Felisola, Bastian Grez, Manuel Morocho-López +4
The polynomial affine model of gravity was proposed as an alternative to metric and metric-affine gravitational models. What at the beginning was thought as a source of unpredictab…
Inflationary scenarios in an effective polynomial affine model of gravity
Oscar Castillo-Felisola, Bastian Grez, Jose Perdiguero +1
In this paper we inquire inflationary scenarios built on a simplified version of the polynomial affine model of gravity. Given the absence of a metric tensor in the formulation of…
Polynomial affine gravity in 3+1 dimensions
José Perdiguero, Oscar Castillo-Felisola
The polynomial affine gravity is an alternative model of gravity whose fundamental field is the affine connection, and it is invariant under the complete group of diffeomorphisms.…
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…
Cosmological solutions to polynomial affine gravity in the torsion-free sector
Oscar Castillo-Felisola, José Perdiguero, Oscar Orellana
We find possible cosmological models of the Polynomial Affine Gravity described by connections that are either compatible or not with a metric. When possible, we compare them with…
