  1. 1. Cosmological models, nonideal fluids and viscous forces in general relativity

    Author : Daniele Gregoris; Kjell Rosquist; Alan Coley; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; gravity; exact model; black hole; friction; Theoretical Physics; teoretisk fysik;

    Abstract : This thesis addresses the open questions of providing a cosmological model describing an accelerated expanding Universe without violating the energy conditions or a model that contributes to the physical interpretation of the dark energy. The former case is analyzed considering a closed model based on a regular lattice of black holes using the Einstein equation in vacuum. READ MORE

  2. 2. Dynamical systems in cosmology and astrophysics

    Author : Ulf Nilsson; Alan Coley; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Physics; Fysik; Physics; fysik;

    Abstract : General relativity is today an important branch of physics. It has, since its publication at the beginning of this century, changed from being of more mathematical than physical interest to one of the most active experimental fields in physics. READ MORE

  3. 3. Cosmological Models and Singularities in General Relativity

    Author : Patrik Sandin; Claes Uggla; Alan Coley; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; general relativity; Bianchi cosmology; singularities; dynamical systems; Fuchsian methods; Hamiltonian methods; Theory of relativity; gravitation; Relativitetsteori; gravitation; Physics; Fysik;

    Abstract : This is a thesis on general relativity. It analyzes dynamical properties of Einstein's field equations in cosmology and in the vicinity of spacetime singularities in a number of different situations. READ MORE
