Each equivalence relation provides a partition of the underlying set into disjoint equivalence classes. Two elements of the given set are equivalent to each other if and only if they belong …

Equivalence classes in set theory, or simply "equivalence classes," are the name given to a subset of some equivalence relation R R which includes all elements equivalent to each other.
