Abstract
Up to now the theory of critical dynamics has remained almost exclusively the domain of analytic mode-coupling and renormalization group theories1, 2. The mode-coupling approach is a selfconsistent method which is capable of a low-order treatment of reversible (nondissipative) couplings, e. g. the strength of precession terms in magnetic systems. The renormalization-group theory goes beyond the modecoupling approach not only because it provides a satisfactory foundation for the concepts of universality and dynamic scaling but also because it permits a systematic higher-order treatment of both reversible and dissipative couplings.KeywordsKinetic CoefficientTricritical PointDynamic ExponentDynamic ScalingMulticritical PointThese keywords were added by machine and not by the authors.
