  1. 1. Relativizing linguistic relativity Investigating underlying assumptions about language in the neo-Whorfian literature

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ingrid Björk; Uppsala universitet.; [2008]
    Nyckelord :Linguistics; Linguistic relativity hypothesis; Sapir-Whorf hypothesis; Language and thought; Neo-Whorfianism; Lingvistik; Linguistics; lingvistik;

    Sammanfattning : This work concerns the linguistic relativity hypothesis, also known as the Sapir-Whorf hypothesis, which, in its most general form claims that ‘lan-guage’ influences ‘thought’. Past studies into linguistic relativity have treated various aspects of both thought and language, but a growing body of literature has recently emerged, in this thesis referred to as neo-Whorfian, that empirically investigates thought and language from a cross-linguistic perspective and claims that the grammar or lexicon of a particular language influences the speakers’ non-linguistic thought.

  2. 2. Perturbative Methods in General Relativity

    Detta är en avhandling från Umeå : Fysik

    Författare :Daniel Eriksson; Umeå universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; General relativity; perturbation theory; photon-photon scattering; cosmology; FRW models with cosmological constant; Bianchi type V; slowly rotating stars; Hartle formalism; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : Einstein's theory of general relativity is a cornerstone in the process of gaining increased understanding about problems of gravitational nature. It can be applied to problems on the huge length scales of cosmology and as far as we know it does not break down before the Planck scale is approached. LÄS MER

  3. 3. Stellar Models in General Relativity

    Detta är en avhandling från Stockholm : Fysikum

    Författare :Lars Samuelsson; Stockholms universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; General relativity; compact objects; neutron stars; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : Neutron stars are some of the most fascinating objects in Nature. Essentially all aspects of physics seems to be represented inside them. Their cores are likely to contain deconfined quarks, hyperons and other exotic phases of matter in which the strong interaction is the dominant force. LÄS MER

  4. 4. At the edge of space and time - exploring the b-boundary in general relativity

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Fredrik Ståhl; Mittuniversitetet.; Mittuniversitetet.; Umeå universitet.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP; MATHEMATICS; MATEMATIK; general relativity; b-boundary; singularity; non-Hausdorff topology; General relativity; differential geometry; b-metric; frame bundle; imprisoned curves;

    Sammanfattning : This thesis is about the structure of the boundary of the universe, i.e., points where the geometric structures of spacetime cannot be continued. In partic­ular, we study the structure of the b-boundary by B. LÄS MER

  5. 5. Cosmological Models and Singularities in General Relativity

    Detta är en avhandling från Karlstad : Karlstad University

    Författare :Patrik Sandin; Karlstads universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; general relativity; Bianchi cosmology; singularities; dynamical systems; Fuchsian methods; Hamiltonian methods; NATURAL SCIENCES Physics Other physics Theory of relativity; gravitation; NATURVETENSKAP Fysik Övrig fysik Relativitetsteori; gravitation; Physics; Fysik;

    Sammanfattning : 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. LÄS MER
