Scalar Field cosmology from a Modified Poisson Algebra
Genly Leon, Alfredo D. Millano, Andronikos Paliathanasis
We investigate the phase space of a scalar field theory obtained by minisuperspace deformation. We consider quintessence or phantom scalar fields in the action which arise from min…
Averaging generalized scalar field cosmologies III: Kantowski--Sachs and closed Friedmann--Lemaître--Robertson--Walker models
Genly Leon, Esteban González, Samuel Lepe +2
Scalar field cosmologies with a generalized harmonic potential and matter with energy density , pressure , and barotropic equation of state (EoS) $p_m=(γ-1)ρ_m, \; γ\in[0…
Averaging Generalized Scalar Field Cosmologies II: Locally Rotationally Symmetric Bianchi I and flat Friedmann-Lemaître-Robertson-Walker models
Genly Leon, Sebastián Cuéllar, Esteban González +3
Scalar field cosmologies with a generalized harmonic potential and a matter fluid with a barotropic Equation of State (EoS) with barotropic index for the Locally Rotationally S…
Averaging Generalized Scalar Field Cosmologies I: Locally Rotationally Symmetric Bianchi III and open Friedmann-Lemaître-Robertson-Walker models
Genly Leon, Esteban González, Samuel Lepe +2
Scalar field cosmologies with a generalized harmonic potential and a matter fluid with a barotropic Equation of State (EoS) with barotropic index for Locally Rotationally Symme…
Einstein-aether models III: conformally static metrics, perfect fluid and scalar fields
Genly Leon, Alfredo Millano, Joey Latta
The asymptotic properties of conformally static metrics in Einstein-aether theory with a perfect fluid source and a scalar field are analyzed. In case of perfect fluid, some relati…
Qualitative analysis of Einstein-aether models with perfect fluid and scalar fields
Alfredo Millano
The space of the solutions of the differential equations resulting from considering matter fluids of scalar field type or perfect fluid in Einstein-aether theory is analyzed. The E…
