Abstract

Quantized solutions of the Wheeler–DeWitt (WDW) equation describing a closed Friedmann–Robertson–Walker universe with a \(\Lambda \) term and a set of massless scalar fields are studied. It is shown that when \(\Lambda \ll 1\) units and the standard in-vacuum state is considered, the wave function of the universe \(\Psi \) behaves as a random quasiclassical field at rather large a, namely, \(1 \ll a \ll {{e}^{{\frac{2}{{3\Lambda }}}}}\) [1].
