We investigate the effects of the generalized uncertainty principle on the inflationary dynamics of the early universe from both the standard and the braneworld viewpoint. We choose the Randall–Sundrum II model as our underlying braneworld scenario. We find that the quantum-gravitational effects lead to a spectral index which is not scale-invariant. Also, the amplitude of density fluctuations is reduced by increasing the strength of quantum-gravitational corrections. However, the tensor-to-scalar ratio increases by incorporation of these quantum gravity effects. We outline possible manifestations of these quantum gravity effects in the recent and future observations.
