Tilted Bianchi Type I Cosmological Models Filled with Disordered Radiation in General Relativity Revisited
General Relativity describes the state in which radiation concentrates around a star. Klein (1948) worked on it and obtained an approximate solution to Einsteinian field equations in spherical symmetry for a distribution of diffused radiation. Many other researchers (Singh and Abdussattar, 1973; Roy and Bali, 1977) have worked on this topic and obtained exact static spherically and cylindricall...
متن کاملTilted Bianchi Type V Bulk Viscous Cosmological Models in General Relativity
A considerable interest has been shown to the study of physical properties of spacetimes which are conformal to certain well known gravitational fields. The general theory of relativity is believed by a number of unknown functions the ten components of g . Hence there is a little hope of finding physically interesting results without making reduction in their number. In conformally flat spaceti...

متن کاملBulk Viscous Bianchi Type VI0 Cosmological Model in the Self-creation Theory of Gravitation and in the General Theory of Relativity
In the second self-creation theory of gravitation and in the general theory of relativity, Bianchi type VI0 cosmological model in the presence of viscous fluid is studied. An exact solution of the field equations is given by considering the cosmological model yields a constant decelerations parameter q=constant and the coefficients of the metric are taken as A(t)=[c1t+c<su...
متن کاملTilted two-fluid Bianchi type I models
In this paper we investigate expanding Bianchi type I models with two tilted fluids with the same linear equation of state, characterized by the equation of state parameter w. Individually the fluids have non-zero energy fluxes w.r.t. the symmetry surfaces, but these cancel each other because of the Codazzi constraint. We prove that when w = 0 the model isotropizes to the future. Using numerica...
