Abstract

We study the cosmological dynamics in a cubic Horndeski theory which admits cosmic inflation as a solution. To this end, we cast the field equations as a dynamical system and show that it admits inflationary era as an attractor. This also supports an existing hypothesis that the most general expansion history should approach the hypersurface of vanishing scalar current.
