【 摘 要 】

The scaling behavior of Model C describing the dynamical behavior of the n-component nonconserved order parameter coupled statically to a scalar conserved density is considered in d-dimensional space. Conditions for the realization of different types of scaling regimes in the (n, d) plane are studied within the field-theoretical renormalization group approach. Borders separating these regions are calculated on the base of high-order RG functions using epsilon expansions as well as by fixed dimension d approach with resummation.
