The Inflaton Effective Potential for General $\epsilon$
  We develop an analytic approximation for the coincidence limit of a massive
scalar propagator in an arbitrary spatially flat, homogeneous and isotropic
geometry. We employ this to compute the one loop corrections to the inflaton
effective potential from a quadratic coupling to a minimally coupled scalar. We
also extend the Friedmann equations to cover potentials that depend locally on
the Hubble parameter and the first slow roll parameter.
