Higher Dimensional Topological Defect Solutions With Massive Scalar Field in General Relativity

Abstract

In this paper, we investigate a ve dimensional Locally Rotationally Symmetric (LRS) Bianchi type- V string cosmological model with massive scalar eld in general relativity. In order to obtain an exact solution of the field equations, we used the following conditions: (i) the shear scalar is proportional to the expansion scalar, resulting in a relationship between metric potentials, and (ii) the average scale factor is proportional to the massive scalar gield, resulting in a power law relationship. In addition, the physical and kinematical parameters are discussed in detail.
