TABLE 1.

Static exponents characterize variables that do not change through time, such as susceptibility, specific heat, and the distribution of correlations. Exponents are taken from (25; 26). Additional exponents and further explanation can be found in the chart in reference (18). Each exponent applies to all systems within the same universality class (e.g. 2-D Ising). An exponent of 0 denotes logarithmic dependence. Dynamic exponents, which are not shown here, characterize the time dependence of variables, and each exponent depends on the details of each system (e.g. 2-D Ising with or without conserved order parameter) (106).
