Show that R is an … WebAnswer. The element in the brackets, [ ] is called the representative of the equivalence class. An equivalence class can be represented by any element in that equivalence class. So, in Example 6.3.2 , [S2] = [S3] = [S1] = {S1, S2, S3}. This equality of equivalence classes will be formalized in Lemma 6.3.1.

For each a, b \in A, a \sim b if and only if [a] = [b]. Two elements of A are equivalent if and only if their equivalence classes are equal. For each a, b \in A, [a] = [b] or [a] \cap [b] = \emptyset. Any two equivalence classes are either equal or they are disjoint.
