 Title: Generalized Uncertainty Principle and Inflation Parameters
 Key Words: Inflation, Generalized Uncertainty Principle, Quantum Gravity Phenomenology
 Abstract: We study the effects of the generalized uncertainty principle on the inflationary dynamics of the early universe in both standard and braneworld scenarios. The braneworld model we used is the Randall-Sundrum II model. We find that the quantum gravitational effects lead to a spectral index which is not scale invariant. Other inflation parameters such as the amplitude of scalar perturbations and the tensor-to-scalar ratio also change in this setup.  These modifications of the inflation parameters are essentially observable in cosmic microwave background radiation.
