Resumo
A method for generating exact solutions of the equations of the scalar field dynamics in the case of flat Friedmann–Robertson–Walker space on the basis of form-invariant transformations is considered. A method for estimating the divergence of the exact and approximate solutions from the number of e-folds and the parameters of the cosmological perturbations is proposed.
