Geometrothermodynamic Cosmology [PDF]
Entropy, 2023 We review the main aspects of geometrothermodynamics, a formalism that uses contact geometry and Riemannian geometry to describe the properties of thermodynamic systems.

Physical and Relativistic Numerical Cosmology [PDF]
Living Reviews in Relativity, 1998 In order to account for the observable Universe, any comprehensive theory or model of cosmology must draw from many disciplines of physics, including gauge theories of strong and weak interactions, the hydrodynamics and microphysics of baryonic matter ...

On General-Relativistic Lagrangian Perturbation Theory and Its Non-Perturbative Generalization
Universe, 2022 The Newtonian Lagrangian perturbation theory is a widely used framework to study structure formation in cosmology in the nonlinear regime. We review a general-relativistic formulation of such a perturbation approach, emphasizing results on an already ...

Relativistic Ermakov–Milne–Pinney Systems and First Integrals
Physics, 2021 The Ermakov–Milne–Pinney equation is ubiquitous in many areas of physics that have an explicit time-dependence, including quantum systems with time-dependent Hamiltonian, cosmology, time-dependent harmonic oscillators, accelerator dynamics, etc.

Relativistic Cosmology with an Introduction to Inflation
Universe, 2021 In this review article, the study of the development of relativistic cosmology and the introduction of inflation in it as an exponentially expanding early phase of the universe is carried out.

Entropy, 2017 Jüttner used the conventional theory of relativistic statistical mechanics to calculate the energy of a relativistic ideal gas in 1911. An alternative derivation of the energy of a relativistic ideal gas was published by Horwitz, Schieve and Piron in ...

Type V singularities with inhomogeneous equations of state
Physics Letters B, 2022 Interest in cosmological singularities has remarkably grown in recent times, particularly on future singularities with the discovery of late-time acceleration of the universe and dark energy.

Relativistic Fractional-Dimension Gravity
Universe, 2021 This paper presents a relativistic version of Newtonian Fractional-Dimension Gravity (NFDG), an alternative gravitational model recently introduced and based on the theory of fractional-dimension spaces.
