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.…
Noncommutative Quantum Cosmology for the FLRW model in Unimodular Gravity
J. A. Astorga-Moreno, Miguel A. García-Aspeitia, E. A. Mena-Barboza
It is well known that classical Unimodular Gravity (UG) is equivalent to General Relativity, but is not clear the equivalence at the quantum level. Here we exhibit, in the UG frame…
Linear perturbations spectra for dynamical dark energy inspired by modified gravity
Celia Escamilla-Rivera, A. Hernández-Almada, Miguel A. García-Aspeitia +1
In this paper, we study a particular modified gravity Equation of State, the so-called Jaime-Jaber-Escamilla, that emerges from the first gravity modified action principle and can…
Numerical Prediction of cusps or kinks in the Nambu-Goto dynamics
Aldrin Cervantes, Miguel A. García-Aspeitia
It is known that Nambu-Goto extended objects present some pathological structures, such as cusps and kinks, during their evolution. In this paper, we propose a model through the ge…
About the Geometric Solution to the Problems of Dark Energy
Miguel Angel García-Aspeitia
In this paper is proposed a geometric solution to the dark energy, assuming that the space can be divided into regions of size and energy . Significantly t…
