The state space defined by selected macroscopic observables or coarse-grained fields. Many microscopically distinct states can correspond to the same macrostate.

This is an authored directed relation from the source endpoint to the target endpoint.
Given selected observables, identify two microstates when all selected macroscopic values agree; the resulting equivalence classes form a precise macrostate quotient. Other coarse-grainings need not be literal quotients.
Identify elements by a stated equivalence relation and equip the quotient with the induced structure. The edge detail must state the representatives and equivalence relation.
wp-physics-microstatewp-physics-thermodynamic-statetong-statistical-physicsThis is an authored directed relation from the source endpoint to the target endpoint.
Selecting macroscopic observables defines a reduced state space for the system; distinct microscopic states can map to the same point in it.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
