Decomposition of the connection in affine models of gravity: Can the connection tell us something about the metric?
Oscar Castillo-Felisola, Bastian Grez, Aureliano Skirzewski +1
In physics geometrical connections are the mean to create models with local symmetries (gauge connections), as well as general diffeomorphisms invariance (affine connections). Here…

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…

Cosmological Solutions in Polynomial Affine Gravity with Torsion
Oscar Castillo-Felisola, Bastian Grez, Gonzalo J. Olmo +2
The Polynomial Affine Gravity is an alternative gravitational model, where the interactions are mediated solely by the affine connection, instead of the metric tensor. In this pape…
