A Non-Linear Type Equation of State and Cosmic Fluid Dynamics

Shouvik Sadhukhan, Alokananda Kar, Surajit Chattopadhyay

In this chapter we have introduced a special type of non-linear equation of state to discuss the cosmological evolution mechanism. The new equation of state is a four parameters mo…

Energy conditions for Inhomogeneous EOS and its Thermodynamics analysis with the resolution on finite time future singularity problems

Alokananda Kar, Shouvik Sadhukhan, Surajit Chattopadhay

In this paper we study two different cases of inhomogeneous EOS of the form p_d = ω(t)ρ_d+w_1 f(H, t) . We derive the energy density of dark fluid and dark matter component for bot…
