CYLINDRICALLY SYMMETRIC INHOMOGENEOUS COSMIC STRINGS AND DOMAIN WALLS IN BIMETRIC RELATIVITY

Abstract

Cylindrically symmetric inhomogeneous universe is studied with thick domain walls and cosmic strings in Bimetric Theory of Relativity .It is observed that, in this theory, thick domain walls and cosmic strings do not exist. As we know that, at the early stage of evolution of the universe domain walls as well as cosmic strings do appear which lead to formation of galaxies .Thus, it may be said that the bimetric relativity does not help to describe the early era of the universe.

Key Words: - cylindrically, inhomogeneous, domain walls, string, bimetric.
