Abstract
Continuing the investigation of the simplest cosmological model with t he massive real scaler noninteracting inflaton field minimally coupled to gravity, we study an influence of the cosmological constant on the behavior of trajectories in closed minisuperspace Friedmann-Robertson -Walker model. Combining numerical calculations with qualitative analy sis both in configuration and phase space we present a convenient clas sification of trajectories.
