Abstract

Homogeneous isotropic gravitating models are discussed in the framework of gauge approach to gravitation. Generalized cosmological Friedmann equations without specific solutions are deduced for models filled by scalar fields and usual gravitating matter. Extreme conditions, by which gravitational repulsion effect takes place, are analyzed.
