Phys. Rev. D 45, 1158–1162 (1992)Mixmaster numerical behavior and generalizationsReceived 19 August 1991; published in the issue dated 15 February 1992 The numerical simulation of the mixmaster universe serves the purpose of suggesting two kinds of results. The intrinsic time evolution, during contraction, will be seen to be nonchaotic. This is a necessary feature of relativistic cosmological models undergoing this kind of motion. The mixmaster model also provides a clue on how to define chaoticity for systems described by nonautonomous sets of differential equations. © 1992 The American Physical Society URL:
