The extended class of exact cosmological solutions based on the Darboux transformations

Бесплатный доступ

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.
