Cosmology under the fractional calculus approach: a possible tension resolution?
Genly Leon, Miguel A. García-Aspeitia, Guillermo Fernandez-Anaya +3
Recently, a new field of study called fractional cosmology has emerged. It uses fractional calculus to modify the standard derivative equations and change the Friedmann equations.…
Exact solutions and cosmological constraints in fractional cosmology
Esteban González, Genly Leon, Guillermo Fernandez-Anaya
This paper investigates exact solutions of cosmological interest in fractional cosmology. Given , the order of Caputo's fractional derivative, and , the matter equation of st…
Scalar field evolution at background and perturbation levels for a broad class of potentials
Genly Leon, Saikat Chakraborty, Sayantan Ghosh +3
In this paper, we investigate a non-interacting scalar field cosmology with an arbitrary potential using the -deviser method that relies on the differentiability properties of t…
A new Parametrization for Bulk Viscosity Cosmology as Extension of the CDM Model
Gabriel Gómez, Guillermo Palma, Ángel Rincón +2
Bulk viscosity in cold dark matter is an appealing feature that introduces distinctive phenomenological effects in the cosmological setting as compared to the CDM model. Under t…
A non-singular early-time viscous cosmological model
Norman Cruz, Esteban González, Jose Jovel
In this paper, we study the thermodynamical and mathematical consistencies for a non-singular early-time viscous cosmological model known as soft-Big Bang, which was previously fou…
Study of a viscous WDM model: Near equilibrium condition, entropy production, and cosmological constraints
Norman Cruz, Esteban González, Jose Jovel
Extensions to a DM model have been explored to face current tensions that occur within its framework, which encompasses broadening the nature of the dark matter (DM) component t…
