We examine effects of the Generalized Uncertainty Principle, predicted by various theories of
quantum gravity to replace the Heisenberg’s uncertainty principle near the Planck scale, on post
inflation preheating in cosmology, and show that it can predict either an increase or a decrease in
parametric resonance and a corresponding change in particle production. Possible implications are
considered.
