WebMay 26, 2024 · We can visualize the above binary relation as a graph, where the vertices are the elements of S, and there is an edge from a to b if and only if aRb, for ab ∈ S. The following are some examples of relations defined on Z. Example 2.1.2: Define R by aRb if and only if a < b, for a, b ∈ Z. Define R by aRb if and only if a > b, for a, b ∈ Z. WebReflexive Relation Examples. Example 1: A relation R is defined on the set of integers Z as aRb if and only if 2a + 5b is divisible by 7. Check if R is reflexive. Solution: For a ∈ Z, 2a + 5a = 7a which is clearly divisible by 7. ⇒ aRa. Since a is an arbitrary element of Z, therefore (a, a) ∈ R for all a ∈ Z.
WebAn example of antisymmetric is: for a relation “is divisible by” which is the relation for ordered pairs in the set of integers. For relation, R, an ordered pair (x,y) can be found where x and y are whole numbers and x is divisible by y. It is not necessary that if a relation is antisymmetric then it holds R (x,x) for any value of x, which ... WebExample. Define a relation on Zby x∼ yif and only if x+2yis divisible by 3. Check each axiom for an equivalence relation. If the axiom holds, prove it. If the axiom does not hold, give a specific counterexample. For example, 2 ∼ 11, since 2+2·11 = 24, and 24 is divisible by 3. And 7 ∼ −8, since 7+2·(−8) = −9, and −9 is ...
