String Cloud and Domain Walls with Quark Matter in Kink Cosmological Model

Abstract

We have studied quark matter coupled with string cloud and domain walls in the context of general relativity. For this purpose, we solved Einstein’s field equations for quark matter coupled to the string cloud and domain walls in spherical symmetric kink space-time. It is found that cosmic strings and domain walls do not survive in this space-time. Hence, the space-time in both the cases reduces to Minkowskian and the space-time is flat.
