Scientific paper

Previous numerical studies of vacuum Bianchi IX cosmologies unwittingly contained ``matter'' having negative energy density, thereby causing erratic oscillations in the three-volume and apparent chaotic behavior of the principal axes. The behaviour with physically acceptable positive or zero energy densities shows the expected monotonically declining three-volume. We show further that the maximal Liapunov characteristic exponent of the phase flow is zero with respect to the time variable that is usually used in investigating this model. Despite this, the deterministic model is unpredictable (the entropy per cycle is large and positive) with respect to the number of Kasner epochs comprising each major cycle.
