Some magnetized bianchi type-III massive string cosmological models in general relativity

Abstract

Some Bianchi type III cosmological models with magnetic field for massive string are investigated. F 12 is only the non-vanishing component of electromagnetic field tensor F i j . To get a determinate solution. we have assumed that the expansion (θ) in the model is proportional to the shear (σ). This leads to C = A n where A and C are functions of time alone. A particular solution for n = 1 is discussed. The physical implications of the models, are also discussed.

Locally rotationally symmetric Bianchi type I cosmology in f(R, T) gravity

“…Wang [68] explored string cosmological models in Kantowski-Sachs spacetime. Magnetized Bianchi type III massive string cosmological models in GR have been investigated by Upadhaya [69]. Hellaby [70] gave a review of some recent developments in inhomogeneous models and it was concluded that the universe is inhomogeneous on many scales.…”
