摘要：
We summarize recent results concerning the evolution of second order perturbations in flat dust irrotational FLRW models with Lambda not equal 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.
