摘要: The renormalization-group method for studying critical phenomena is generalized to a class of dynamical systems---the time-dependent Ginzburg-Landau models. effects conservation laws on the dynamics are investigated through study models with different properties energy and space integral order parameter. Dynamic exponents near four dimensions ($d\ensuremath{\approx}4$) obtained from recursion relations, analogous those Wilson Fisher. physical significance explored applicability results experiments NMR linewidth Fe${\mathrm{F}}_{2}$ discussed.
