    Nature of the singularities in higher dimensional husain spacetime
    (2006-06-10) Patil, K. D.; Zade, S. S.
    We generalize the previous studies of the spherically symmetric gravitational collapse in four dimensional spacetime to higher dimensions. It is found that the central singularities may be naked in higher dimensions but depend sensitively on the choices of the parameters. These naked singularities are found to be gravitationally strong that violate the cosmic censorship hypothesis.

    Spherical and non-spherical gravitational collapse in monopole-anti-de sitter-vaidya spacetime
    (2006-08-10) Patil, K. D.; Thool, U. S.
    In the present work, we investigate the influence of the monopole field on the occurrence of the spacetime singularities in the gravitational collapse of anti-de Sitter-Vaidya spacetime. It has been found that the spherically symmetric monopole anti-de Sitter-Vaidya spacetime contradicts the CCH, whereas the non-spherical collapse respects it.
