- Title
Observational constraints on emergent universe model with non-linear viscous fluid.

- Abstract
A flat emergent universe (EU) with a non-linear equation of state ( p = A ρ + f (ρ) ) is studied considering bulk viscosity. In the paper we obtain cosmological models with viscous fluid described by truncated Israel–Stewart theory. Using autonomous system of field equations the stability of the solutions are analyzed. The observational constraints on the model parameters are determined for different matter energy compositions of the universe with non-linear viscosity in the EU scenario.
