Second Order Perturbations of Flat Dust FLRW Universes with a Cosmological Constant
Felipe C. Mena, Reza Tavakol, Marco Bruni
Abstract
We summarize recent results concerning the evolution of second order perturbations in flat dust irrotational FLRW models with Λ 0. We show that asymptotically these perturbations tend to constants in time, in agreement with the cosmic no-hair conjecture. We solve numerically the second order scalar perturbation equation, and very briefly discuss its all time behaviour and some possible implications for the structure formation.
