    Författare :Katharina Maria Radermacher; Hans Ringström; James Isenberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cosmic Censorship; Cosmic No-Hair; Big Bang; symmetry; Bianchi; T2-symmetry; Gowdy; general relativity; cosmology; late time; initial time; asymptotic behaviour; perfect fluid; scalar field; Einstein equations; Mathematics; Matematik;

    Sammanfattning : This thesis consists of three articles investigating the asymptotic behaviour of cosmological spacetimes with symmetries arising in Mathematical General Relativity.In Paper A and B, we consider spacetimes with Bianchi symmetry and where the matter model is that of a perfect fluid.

  4. 3. On the cylindrically symmetric Einstein-Vlasov system

    Författare :Mikael Fjällborg; []
    Nyckelord :;

    Sammanfattning : For the cylindrically symmetric ''asymptotically flat'' Einstein equations in the case of electro-vacuum it is known that solutions exist globally and even that this class of spacetimes are causally geodesically complete. Hence the strong cosmic censorship holds for this class. LÄS MER

  5. 4. Dynamical systems in cosmology and astrophysics

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

    Sammanfattning : 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. LÄS MER
