This phenomenon takes place when a mild non-convexity 211inequality is satisfied by the potential V(mu). The presence of such a period of 211Mu-oscillation-driven inflation can substantially modify reheating scenarios. In 211some models the effect of these fast oscillations might be imprinted on the 211promordial perturbation spectrum at cosmological scales. 收起
