Some Studies on Relativistic Cosmology (Paperback)

In this book, we have studied the geometrical aspects of the space-time with regard to the space of constant curvature, symmetric space and recurrent space, constructed the spherically symmetric homogeneous cosmological model in Einstein's theory of gravitation and the space-time is designed as degenerate vacuum universe when c = 0, the problem of spherically symmetric homogenous space time with perfect fluid and viscous fluid distribution are considered separately in Einstein's theory, the inhomogeneous plane symmetric space-time in presence of macro matter field representing perfect fluid in Einstein's theory, to construct the plane symmetric inhomogeneous Masonic perfect fluid models in Einstein's theory in presence of micro and macro matter field represented by scalar meson field and perfect fluid respectively obtained Bianchi type -1 spatially homogeneous and isotropic cosmological model in Einstein's theory and its modified theory proposed by Barber in presence of perfect fluid distribution, devoted to study the spatially homogeneous and anisotropic Bianchi type-1 space time with perfect fluid distribution in Barber's second theory of gravitation etc.
