  • STRING COSMOLOGIES - INSPIRE
    A model of a cloud formed by massive strings is studied in the context of the usual general relativity This model is used as a source of Bianchi type I and "Kantowski-Sachs" type of cosmological models Some global properties of the above-mentioned cosmological models are studied for the equation of state (energy density) ∝ (tension density)

    SummaryThe author's gauge-invariant model of a cloud of strings is generalized by considering a pressure or a tension produced by the strings that form the cloud The energy conditions for the model are investigated The general solution to Einstein equations coupled to a «fluid» of strings with spherical symmetry is presented The Petrov-Pirani type, as well as the embedding class of the
