• SPHERICAL SYMMETRIC COSMOLOGICAL MODEL WITH COSMIC STRINGS COUPLED WITH PERFECT FLUID IN BIMETRIC RELATIVITY
Abstract
Spherical symmetric Kantowski –Sachs space-time is studied in Rosen’s bimetric relativity, considering the source of gravitation as cosmic strings coupled with perfect fluid distribution.It is shown that a macro cosmological model represented by cosmic string coupled with perfect distribution does not exist and only a vacuum model can be constructed.
Keywords
Spherical symmetric, Kantowski-Sachs model, cosmic string.
