Inflationary predictions of Geometric Inflation
Gustavo Arciniega, Luisa Jaime, Gabriella Piccinelli
In the framework of gravitational models obtained from the Geometric Inflation's proposal, where an infinite tower of curvature scalars are included into the action, we compute the…
Geometric Inflation
Gustavo Arciniega, Pablo Bueno, Pablo A. Cano +3
We argue that the presence of an inflationary epoch is a natural, almost unavoidable, consequence of the existence of a sensible effective action involving an infinite tower of hig…
Lemaitre-Tolman-Bondi dust solutions in f(R) gravity
Roberto A Sussman, Luisa G Jaime
We derive a class of non-static inhomogeneous dust solutions in f(R) gravity described by the Lemaitre-Tolman-Bondi (LTB) metric. The field equations are fully integrated for all p…
Diagnostic of under the function
Luisa G. Jaime
We perform the twopoint diagnostic for the function proposed by Sahni in 2014 for the Starobinsky and Hu & Sawicki models in gravity. We show that t…
Cosmology in f(R) exponential gravity
Luisa Jaime, Marcelo Salgado, Leonardo Patino
Using an approach that treats the Ricci scalar itself as a degree of freedom, we analyze the cosmological evolution within an f(R) model that has been proposed recently (exponentia…
