TL;DR
This paper analyzes the emergence of singularities in FLRW cosmological models near w=-1, examining how small deviations influence the universe's scale factor and potential singularity formation.
Contribution
It provides a detailed analysis of singularity formation in FLRW models close to w=-1, linking small deviations in w to the universe's scale factor behavior.
Findings
Singularities can form in FLRW models near w=-1 due to small deviations.
The relationship between deviations in w and the scale factor is characterized.
Conditions for singularity formation are identified.
Abstract
In this talk we would like to analyse the appearance of singularities in FLRW cosmological models which evolve close to w=-1, where w is the barotropic index of the universe. We relate small terms in cosmological time around w=-1 with the correspondent scale factor of the universe and check for the formation of singularities.
