摘要：

We investigate the simplest cosmological model with the massive real scalar noninteracting inflaton held minimally coupled to gravity. The classification of trajectories in closed minisuperspace Fiedmann-Robertson-Walker model is presented. The possible fractal nature of a set of infinitely bounced trajectories is discussed. The results of numerical calculations are compared with those obtained by perturbative analytical calculations around the exactly solvable minisuperspace cosmological model with massless scalar held.
