A Time Varying Strong Coupling Constant as a Model of Inflationary Universe

We consider a scenario where the strong coupling constant was changing in the early universe. We attribute this change to a variation in the colour charge within a Bekenstein-like model. Treating the vacuum gluon condensate < G 2 > as a free parameter , we could generate inflation, similar to a chaotic inflation scenario, with the required properties to solve the fluctuation and other standard cosmology problems. A possible approach to end the inflation is suggested.
