Bianchi type VI_0 cosmology with purely magnetic and purely electric space time

摘要

In General Relativity, the electric (E_(αβ)) and magnetic (H_(αβ)) parts of Weyl tensor are the gravitational quantities that play an analogous role to the electric and magnetic fields in classical electromagnetism. The present study deals with Bianchi type VI_0 cosmological model with purely magnetic (PM) and purely electric (PE) space time. Conditions of PM (PE) solutions satisfy E_(αβ) = 0, H_(αβ) ≠ 0 (H_(αβ) = 0, E_(αβ)≠ 0). We present a new class of cosmological model with PM and PE solutions when the source of gravitation is perfectly fluid. Some physical and geometrical properties of the models are also discussed.
