Chaotical dynamics is studied in different Friedmann-Robertson-Walker cosmological models with a scalar (inflaton) field and hydrodynamical matter. The topological entropy is calculated for some particular cases. The suggested scheme can be easily generalized for a wide class of models. Different methods of calculating the topological entropy are compared.
