WebApr 9, 2024 · Solution: Consider, x ∈ S. Then x – x= 0. Zero is divisible by 5. Since x R x holds for all the elements in set S, R is a reflexive relation. Example 4: Consider the set A in which a relation R is defined by ‘m R n if and only if m + 3n is divisible by 4, for x, y ∈ A. Show that R is a reflexive relation on set W. WebIn discrete Maths, an asymmetric relation is just the opposite of symmetric relation. In a set A, if one element is less than the other, satisfies one relation, then the other element is not less than the first one. Hence, less than (<), greater than (>) and minus (-) are examples of asymmetric. We can also say, the ordered pair of set A ...
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. WebStrict weak ordering – a strict partial order in which incomparability is an equivalence relation; Total ordering – a connected (total), antisymmetric, and transitive relation; Counting transitive relations. No general formula that counts the number of transitive relations on a finite set (sequence A006905 in the OEIS) is known.
