THE EXTENDED CLASS OF EXACT COSMOLOGICAL SOLUTIONS BASED ON THE DARBOUX TRANSFORMATIONS

Fomin I.V.

Form-invariant transformations of the equations of cosmological dynamics for inflationary models with a scalar field based on Einstein gravity are considered. Based on a combination of various form-invariant transformations, extended Darboux transformations are obtained. A method for constructing chains of exact solutions of the equations of cosmological dynamics based on this transformations is considered.

Keywords: cosmological models, scalar field, relic gravitational waves
