Abstract
Chaotical dynamics is studied in different Friedmann-Robertson-Walker cosmo logical models with a scalar (inflaton) field and hydrodynamical matter. Th e topological entropy is calculated for some particular cases. The suggeste d scheme can be easily generalized for a wide class of models. Different me thods of calculating the topological entropy are compared. [S0556-2821(99)0 4710-4].
