Relations in a Set:

Let consider R be a relation from A to B. If B = A, then R is known as a relation in A. Thus relation in a set A is a subset of A ΧA.

Identity Relation:

R is an identity relation if (a, b) € R iff a = b, a € A, b € A. In other terms, every element of A is belongs to only itself.

Universal Relation in a Set:
