A class of systems sharing long-distance scaling functions and critical exponents despite different microscopic details. Spatial dimension, symmetry, interaction range, and conserved quantities are among the data that can distinguish classes.

This is an authored directed relation from the source endpoint to the target endpoint.
Critical exponents and scaling functions classify long-distance critical behavior into universality classes that can ignore many microscopic details.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

Systems whose coarse-grained couplings flow toward the same infrared fixed point can share critical exponents and scaling functions, while dimensionality, symmetry, interaction range, and conserved dynamics can separate universality classes.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
