Dust Solution - Examples

Examples

Noteworthy individual dust solutions include:

  • Friedmann–Lemaître–Robertson–Walker (FLRW) dusts (homogeneous and isotropic solutions often referred to as the matter-dominated FLRW models)
  • Kasner dusts (the simplest cosmological model exhibiting anisotropic expansion)
  • Bianchi dust models (generalizations of FLRW and Kasner models, exhibiting various types of Lie algebras of Killing vector fields)
  • Lemaître–Tolman–Bondi (LTB) dusts (some of the simplest inhomogeneous cosmological models, often employed as models of gravitational collapse)
  • Kantowski-Sachs dusts (cosmological models which exhibit perturbations from FLRW models)
  • van Stockum dust (a cylindrically symmetric rotating dust)
  • the Neugebauer-Meinel dust (which models a rotating disk of dust matched to an axisymmetric vacuum exterior; this solution has been called, with some justice, the most remarkable exact solution discovered since the Kerr vacuum)
  • Gödel metric

Famous quotes containing the word examples:

    “In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.”
    —Michel de Montaigne (1533–1592)

    “No rules exist, and examples are simply life-savers answering the appeals of rules making vain attempts to exist.”
    —André Breton (1896–1966)

    “It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”
    —G.C. (Georg Christoph)
