Creation of gravitons near the cosmological singularity

Equations are obtained for the local rate of creation of gravitons in a Friedmann universe, filled with a relativistic perfect gas consisting of particles with nonzero rest mass. It is shown that as the singularity is approached, when 3P, the rate of creation increases as the energy density in the universe and can for this reason become arbitrarily large.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 4, pp. 95–98, April, 1981.
