Notes:
In the presence of a nonzero cosmological constant Λ, we classify the anisotropic cosmological models of the Kantowski–Sachs type by means of the quantities ε20, q0, ∑0 corresponding, respectively, to the relative root-mean-square deviation from isotropy, the deceleration parameter, and the density parameter of the perfect fluid at a given time t=t0. We obtain for Λ〉0 a set of big-bang models of zero measure as well as a set of cosmological models of nonzero measure evolving toward the de Sitter solution.
