Dynamics and observational signatures of warm Dirac–Born–Infeld inflation with nonminimal derivative coupling

Abstract This paper investigates a warm Dirac–Born–Infeld (DBI) inflationary model with nonminimal derivative coupling (NMDC) to gravity, where the inflaton kinetic term interacts with the Einstein tensor, thereby improving the effective gravitational friction. This model seamles...
