Consistency of anisotropic inflation during rapid oscillations with Planck 2015 data
This paper is aimed to study the compelling issue of cosmic inflation during rapid oscillations using the framework of non-minimal derivative coupling. To this end, an anisotropic and homogeneous Bianchi I background is considered. In this context, I developed the formalism of anisotropic oscillatory inflation and found some constraints for the existence of inflation. In this era, the parameters related to cosmological perturbations are evaluated, further, their graphical trajectories are presented to check the compatibility of the model with the observational data (Planck 2015 probe).
