Completeness and singularities in some inhomogeneous cosmologies

It is shown that the inhomogeneous generalization of the Ellis-MacCallum family of Bianchi cosmological models of Wainwright {ital et} {ital al}. was given in an incomplete chart. The behavior of these models on the boundary of the chart is studied. Singularities are found in some cases and the gene...

Description
Summary:It is shown that the inhomogeneous generalization of the Ellis-MacCallum family of Bianchi cosmological models of Wainwright {ital et} {ital al}. was given in an incomplete chart. The behavior of these models on the boundary of the chart is studied. Singularities are found in some cases and the general completeness of the manifolds is discussed.
