Hamilton-Jacobi Mechanics from Pseudo-Supersymmetry [PDF]
, 2007 For a general mechanical system, it is shown that each solution of the Hamilton-Jacobi equation defines an N=2 pseudo-supersymmetric extension of the system, such that the usual relation of the momenta to Hamilton's principal function is the `BPS ...

Ricci cosmology in light of astronomical data
European Physical Journal C: Particles and Fields, 2021 Recently, a new cosmological framework, dubbed Ricci cosmology, has been proposed. Such a framework has emerged from the study of relativistic dynamics of fluids out of equilibrium in a curved background and is characterised by the presence of deviations

About the Infinite Repetition of Histories in Space
Theoria, 2014 This paper analyzes two different proposals, one by Ellis and Brundrit, based on classical relativistic cosmology, the other by Garriga and Vilenkin, based on the DH interpretation of quantum mechanics, both concluding that, in an infinite universe ...

Integration the relativistic wave equations in Bianchi IX cosmology model [PDF]
Компьютерные исследования и моделирование, 2016 We consider integration Clein-Gordon and Dirac equations in Bianchi IX cosmology model. Using the noncommutative integration method we found the new exact solutions for Taub universe. Noncommutative integration method for Bianchi IX model is based on the

The Structure and Interpretation of Cosmology: Part I - General Relativistic Cosmology
, 2004 The purpose of this work is to review, clarify, and critically analyse modern mathematical cosmology. The emphasis is upon mathematical objects and structures, rather than numerical computations. This paper concentrates on general relativistic cosmology.

Einstein's cosmology review of 1933: a new perspective on the Einstein-de Sitter model of the cosmos [PDF]
, 2015 We present a first English translation and analysis of a little-known review of relativistic cosmology written by Albert Einstein in late 1932. The article, which was published in 1933 in a book of Einstein papers translated into French, contains a ...

Newtonian versus relativistic nonlinear cosmology
, 2005 Both for the background world model and its linear perturbations Newtonian cosmology coincides with the zero-pressure limits of relativistic cosmology.

, 2005 I review various ideas on MOND cosmology and structure formation beginning with non-relativistic models in analogy with Newtonian cosmology. I discuss relativistic MOND cosmology in the context of Bekenstein's theory and propose an alternative biscalar ...

Newtonian and Post-Newtonian approximations of the k = 0 Friedmann Robertson Walker Cosmology [PDF]
, 1999 In a previous paper we derived a post-Newtonian approximation to cosmology which, in contrast to former Newtonian and post-Newtonian cosmological theories, has a well-posed initial value problem.
