Abstract: We consider inflationary models with the inflaton coupled to the Gauss-Bonnet term assuming a special relation ${\ensuremath{\delta}}_{1}=2\ensuremath{\lambda}{\ensuremath{\epsilon}}_{1}$ between the two slow-roll parameters ${\ensuremath{\delta}}_{1}$ and ${\ensuremath{\epsilon}}_{1}$. For the slow-roll inflation, the assumed relation leads to the… read more here.
