Alexey V. Toporensky
TL;DR
This paper investigates chaotic behavior in a scalar field cosmological model, showing how the type of chaos depends on the potential and identifying conditions where chaos disappears.
Contribution
It introduces a detailed analysis of chaotic regimes in scalar field cosmology and how potential steepness influences chaos presence.
Findings
Two distinct chaotic regimes identified
Chaos depends on scalar field potential shape
Chaos disappears with steep potentials or large cosmological constant
Abstract
A transient chaos in a closed FRW cosmological model with a scalar field is studied. We describe two different chaotic regimes and show that the type of chaos in this model depends on the scalar field potential. We have found also that for sufficiently steep potentials or for potentials with large cosmological constant the chaotic behavior disappears.
