“…A number of problems such as the horizon problem, flatness problem, and singularity problem etc crop up when one probes the early Universe in the framework of the Big Bang model. These can, however, be resolved by evoking a phase of inflation [2][3][4][5][6][7][8][9] at a very early epoch. Furthermore, it is known that the large-scale structure formation of the Universe can be successfully addressed in this scenario.…”

We investigate the emergent universe scenario in the presence of interacting fluids. The non-linear equation of state (EoS) considered in the general theory of relativity for obtaining emergent universe is effectively a cosmological model with a composition of three fluids. In this paper we consider two models to realize viable cosmological scenarios, viz., (i) a two-fluid model with interaction of a pressureless fluid with the fluid having the non-linear EoS needed for the emergent universe, and (ii) a threefluid model with interaction among the three fluids which originate from the EoS of the emergent universe. It is found that realistic cosmological models in accordance with observations are not ruled out for both the above cases. We further show that the generalized second law of thermodynamics is found to hold good in the emergent universe with interacting fluids.
