Constant-roll inflation with non-minimally derivative coupling

Jie Liu, Yungui Gong, Zhu Yi

We investigate the constant-roll inflation with non-minimally kinetic coupling to the Einstein tensor. With the slow-roll parameter $\hat{I}{\cdot }_{\ddot{I}}•=-\ddot{\ddot{I}}•/(H\dot{\ddot{I}}•)$ being a constant, we…
