Perturbations in anisotropic universe models with evolving dark energy

This paper investigates the growth of perturbations in anisotropic cosmological models with evolving dark energy. It considers Bianchi Type-I spacetimes filled with viscous matter and time-varying cosmological and gravitational constants. The evolution of over-densities is analyzed to understand the formation of large-scale structures. Findings suggest viscosity and varying constants impact structure growth rates compared to the standard model.
