Multi-fluid cosmology in Einstein gravity: analytical solutions
Valerio Faraoni, Sonia Jose, Steve Dussault
We review analytical solutions of the Einstein equations which are expressed in terms of elementary functions and describe Friedmann-Lemaître-Robertson-Walker universes sourced by…
Analogies between logistic equation and relativistic cosmology
Steve Dussault, Valerio Faraoni, Andrea Giusti
We develop several formal analogies between the logistic equation and the spatially homogeneous and isotropic relativistic cosmology described by the Einstein-Friedmann equations.…
A new symmetry of the spatially flat Einstein-Friedmann equations
Steve Dussault, Valerio Faraoni
We report a new symmetry of the Einstein-Friedmann equations for spatially flat Friedmann- Lemaître-Robertson-Walker universes. We discuss its application to barotropic perfect flu…
Cosmological analogies, Lagrangians, and symmetries for convective-radiative heat transfer
Valerio Faraoni, Farah Atieh, Steve Dussault
A formal analogy between the Friedmann equation of relativistic cosmology and models of convective-radiative cooling/heating of a body (including Newton's, Dulong-Petit's, Newton-S…
