renormalization group methods

[rē‚nȯr·mə·lə′zā·shən ¦grüp ‚meth·ədz] (statistical mechanics) Methods for treating the behavior of substances near critical points, in which the canonical ensemble is generalized by dividing a substance into cells of arbitrary size and forming an ensemble consisting of all microscopic configurations consistent with specified values of the thermodynamic variables in each of these cells.
