Quantum Kinetic Equations and Cosmology
Oleg A. Fonarev
Abstract
We analyse quantum--kinetic effects in the early Universe. We show that quantum corrections to the Vlasov equation give rise to a dynamical variation of the gravitational constant. The value of the gravitational constant at the Grand Unification epoch is shown to differ from its present value to about 10-4 ÷10-3 \% .
