Phys. Rev. D 20, 1772–1782 (1979)Quantum effects in the early universe. II. Effective action for scalar fields in homogeneous cosmologies with small anisotropyReceived 16 April 1979; published in the issue dated 15 October 1979 The one-loop contributions of conformally invariant scalar fields to the effective action are calculated for homogeneous cosmological models with small anisotropy. The dynamical equations which determine the classical geometry are displayed and the matrix elements of the stress-energy tensor between the initial and final vacuums are determined. © 1979 The American Physical Society URL:
