Inflationary scenarios in an effective polynomial affine model of gravity
Resumen:
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 the model, we build a kinetic term contracting the derivatives of scalar field with the most general (2, 0)-tensor density build using the affine connection, and introduce a self-interacting potential via a scaling of the volume form. We analyse the cosmological solutions derived from this setup.
