Abstract
Yang-Mills color fields evolve chaotically in an anisotropically expanding universe. The chaotic behavior differs from that found in anisotropic mixmaster universes. The universe nears isotropy at late times, approaching the mean expansion rate of a radiation-dominated universe. However, small chaotic oscillations of the shear and color stresses continue indefinitely. An invariant characterization of the chaos is provided by means of fractal basin boundaries.
