Tilted 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 spacetime the number of unknown functions is reduced to one. The conformally flat metrices are of particular interest in view of their degeneracy in the context of Petrov classification. A number of conformally flat physically significant spacetimes are known like Schwarzschild interior solution and Lemâitre cosmological universe.
