Description

We consider the multifield models and modified gravity theories associated with them. Generalization of the superpotential method to multifield cosmological models is performed and the method of construction of exact solutions is developed. New classes of exact solutions in the two-component models connected with a f(R) gravity model with an additional scalar field have been constructed. and hyperbolic Hubble parameters.
