Bianchi type-I massive string magnetized barotropic perfect fluid cosmological model in bimetric theory

Abstract: Bianchi type-I massive string cosmological model for perfect fluid distribution in the presence of magnetic field is investigated in Rosen's [Gen. Relativ. Gravit. 4, 435 (1973)] bimetric theory of gravitation. To obtain the deterministic model in terms of cosmic time, we have used the condition A = (BC) n , where n is a constant, between the metric potentials. The magnetic field is due to the electric current produced along the x-axis with infinite electrical conductivity. Some physical and geometrical proper… Show more

“…Pawar et al [15,16] examined the perfect fluid string and viscous fluid string cosmological models and obtained the deterministic solutions to field equations within the context of f(T) gravity. Katore et al [17] inspected a massive string-magnetized perfect fluid universe in the bimetric theory of gravitations. Zia et al [18] have obtained the transit dark energy model with perfect fluid using generalized hybrid expansion low in the frame of reference to f(R,T) gravity.…”

“…Rosen [14][15] [25] and Mohanty et al [26],Katore et al [27] ,Sahoo and Mishra [28,29] and Sahoo et al [30] are some of the authors, who have studied various aspects of bimetric theory in different angles. In spite of the fact that many good works have been done, it is evident from literature that there is need for further investigation which may unravel some of the hidden secrets of the theory.…”
