On the possibility of detecting relic gravitational waves in different models of cosmological inflation with Gauss-Bonnet scalar

In this paper a new exact solution of the equations of cosmological dynamics in the framework of GR is considered and it is shown that it can be extended to the case of EGB gravity. Also the energy density of relic gravitational waves is estimated, the possibility of their registration on the detectors LIGO, LISA, DECIGO.
