Abstract: The cosmological dynamics of a closed isotropic Universe filled by a scalar field is considered. We describe three different global regimes which exist in this model. Two of them include a chaotic behavior. Using Poncare section method we show that one of these regimes containes islands of quasiperiodic trajectories.
