چکیده

Two new cylindrically symmetric inhomogeneous string cosmological models are investigated in presence of magnetic field. We have assumed that F12 is the only non-vanishing component of electromagnetic field tensor Fij . The Maxwell’s equations show that F12 is the function of x alone whereas the magnetic permeability μ̄ is the function of x and t both. To get the deterministic solution, it has been assumed that the metric coefficients are separable in the form as A = f(x) (t), B = g(x)k(t), C = g(x)ν(t). Also, the Einstein field equations have been solved with string source in which magnetic field is absent. Some physical and geometric aspects of the models in presence and absence of magnetic field are discussed. c © Electronic Journal of Theoretical Physics. All rights reserved.

Inhomogeneous Perfect Fluid Universe with Electromagnetic Field in Lyra Geometry

A new class of cylindrically symmetric inhomogeneous cosmological models for perfect fluid distribution with electromagnetic field is obtained in the context of Lyra’s geometry. We have obtained two types of solutions by considering the uniform as well as time dependent displacement field. The source of the magnetic field is due to an electric current produced along the z-axis.Only F12 is a non...

A plane-symmetric inhomogeneous cosmological model of perfect fluid distribution with electro-magnetic field is obtained. The source of the magnetic field is due to an electric current produced along the z-axis. F12 is the non-vanishing component of electromagnetic field tensor. To get a deterministic solution, we assume the free gravitational field is Petrov type-II non-degenerate. The behavio...
