Critical Exponent - Scaling Relations

Scaling Relations

Thus, the exponents above and below the critical temperature, respectively, have identical values. This is understandable, since the respective scaling functions, originally defined for, should become identical if extrapolated to

Critical exponents are denoted by Greek letters. They fall into universality classes and obey the scaling relations

These equations imply that there are only two independent exponents, e.g., and . All this follows from the theory of the renormalization group.
