Perturbations in Bianchi-V Spacetimes with Varying Λ, G and Viscous Fluids

As a follow-up of recent article in which we investigated the cosmological background expansion history universe Bianchi type-V models with bulk viscous fluid and evolving Λ Newtonian G parameters, study evolution perturbations current work. In particular, analyse matter over-density that leads to formation large-scale structures Bianchi-V model, compare results standard ΛCDM solutions. Our suggest introducing described by geometry amplifies structure-growth rate.
