Abstract
Cosmological inflation models based on Einstein–Gauss–Bonnet (EGB) gravity with a nonminimal coupling of the scalar field and the Gauss–Bonnet (GB) scalar in the four-dimensional Friedmann–Robertson–Walker universe are considered. A method for construction of exact solutions based on the relationship between these models and the standard inflation with Einstein gravity is presented.
