Query: Stability of Accelerated Expansion in Nonlinear Electrodynamics   This paper is devoted to study the phase space analysis of isotropic and
homogenous universe model by taking a noninteracting mixture of electromagnetic
and viscous radiating fluids whose viscous pressure satisfies a nonlinear
version of the Israel-Stewart transport equation. We establish an autonomous
system of equations by introducing normalized dimensionless variables. In order
to analyze stability of the system, we find corresponding critical points for
different values of the parameters. We also evaluate power-law scale factor
whose behavior indicates different phases of the universe model. It is
concluded that bulk viscosity as well as electromagnetic field enhances the
stability of accelerated expansion of the isotropic and homogeneous universe
model.
