Abstract
The paper considers the creation of particles from a vacuum in a closed, open, and quasi-Euclidean Friedmann model. Finite general expressions are obtained for the density of the number of pairs created, and also new analytical estimates are given of the intensity of processes of creation at different stages of evolution of the universe.
