    Abstract: In this paper, we have studied Friedmann-Robertson-Walker (FRW) cosmological model with quadratic equation of state and cosmological constant in the presence of perfect fluid source in f (R, T) gravity. To obtain an exact solution of the field equations of the theory, we have used quadratic equation of state and time dependent deceleration paramete... Show More

    Abstract: The paper presents analytical study on the effect of ambipolar diffusion on the flow of a two-component plasma gas in the Earth’s Planetary Ionosphere as a model to examine the ions-neutral and electrons-neutral atom interactions. The problem which consists of a set of partial non-linear differential equations was addressed using a plane wave and p... Show More
