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.1158-1162engArtigo10.1103/PhysRevD.45.1158WOS:A1992HE35200017Acesso abertoWOSA1992HE35200017.pdf
