Averaging of the Equations of the Standard Cosmological Model over Rapid Oscillations: Influence of the Cosmological Term on the Mean Value of the Effective Barotropic Coefficient

  • Published:
Russian Physics Journal Aims and scope

With the help of an applied software package written by the authors, we have averaged the effective total barotropic coefficient κ = (–λ + p)/(λ + ε) of the classical scalar field and the cosmological term and have shown that during cosmological evolution for sufficiently large values of the cosmological constant the Universe transitions from the inflationary stage to a nonrelativistic stage, and then, after a plateau, it transitions to a later inflationary stage.
