Inflection Points and the Power Spectrum
  Inflection point inflation generically includes a deviation from slow-roll
when the inflaton approaches the inflection point. Such deviations are shown to
be generated by transitions between singular trajectories. The effects on the
power spectrum are studied within the context of universality classes for
small-field models. These effects are shown to scale with universality
parameters, and can explain the anomalously low power at large scales observed
in the CMB. The reduction of power is related to the inflection point's basin
of attraction. Implications for the likelihood of inflation are discussed.
