Resumen:
We use the Bogoliubov formalism to study both particles and gravitons creation at the reheatingepoch, after a phase transition from inflation to a radiation-dominated universe. The modes of the inflaton field fluctuations and the scalar fluctuations of the metric at the end of inflation are obtained by using a recently introduced formalism related to the Induced Matter theory of gravity. The interesting result is that the number of created particles is bigger than 10^(90) on cosmological scales. Furthermore, the number of gravitons are nearly 10^(-17) times smaller than the number of created particles. In both cases, these numbers rapidly increase on cosmological scales.
