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 ...

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.

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 ...

, 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 ...

A geometrical approach to nonlinear perturbations in relativistic cosmology [PDF]
, 2010 We give a pedagogical review of a covariant and fully non-perturbative approach to study nonlinear perturbations in cosmology. In the first part, devoted to cosmological fluids, we define a nonlinear extension of the uniform-density curvature ...

General Relativistic Self-Similar Solutions in Cosmology [PDF]
, 2006 We present general relativistic solutions for self-similar spherical perturbations in an expanding cosmological background of cold pressure-less gas. We focus on solutions having shock discontinuities propagating in the surrounding cold gas. The pressure,

Non-equilibrium field theory [PDF]
, 2000 I discuss various topics in relativistic non-equilibrium field theory related to high energy physics and cosmology. I focus on non-perturbative problems and how they can be treated on the lattice.Comment: Plenary talk given at the 18th International ...
