Bianchi Type-III Cosmic Strings and Domain Walls Cosmological Model in General Relativity

摘要

Bianchi type-III space time is considered in the presence of cosmic strings and thick domain walls source in the frame work of general relativity. Exact cosmological models using various cases of p = and p = yp are presented. It is observed that the behavior of these models (with cosmic strings and domain walls), based on their physical and kinematical properties, is found to be identical.
