Query: Realization of Power-Law Inflation & Variants via Variation of the
  Strong Coupling Constant   We present a model of power law inflation generated by variation of the
strong coupling constant. We then extend the model to two varying coupling
constants which leads to a potential consisting of a linear combination of
exponential terms. Some variants of the latter may be self-consistent and can
accommodate the experimental data of the Planck 2015 and other recent
experiments.
