Some specific relations. The full relation on set E is the set E E. The full relation is true for all pairs. The identity relation on set E is the set ( x, x ) xE. The identity relation is true for all pairs whose first and second element are identical.Example 1: The lessthanorequalto relation on the set of integers I is a partial order, and the set I with this relation is a poset. Example 2: The subset relation on the power set of a set, say 1, 2, is also a partial order, and the set 1, 2 with the subset relation is a poset. reflexive set relation example

Solved example of reflexive relation on set: 1. A relation R is defined on the set Z (set of all integers) by aRb if and only if 2a 3b is divisible by 5, for all a, b Z. Examine if R is a reflexive relation on Z.

How can the answer be improved? Binary Relations Problem Set Two checkpoint due in the box up front if you're using a late period. Example: the relation a b over Formally: a binary relation R over a set A is reflexive iff for all x A, the relation xRx holds.reflexive set relation example The Transitive Closure. Definition: Let R be a binary relation on a set A. The transitive closure of R is the binary relation R t on A satisfying the following three properties: 1. R t is transitive; 2. R is a subset of R t; 3. If S is any other transitive relation that contains R, then S contains R t.

For example, loves is a nonreflexive relation: there is no logical reason to infer that somebody loves herself or does not love herself. Equivalence. A relation R is an equivalence iff R is transitive, symmetric and reflexive. Reflexive relation. A relation R on a set A is said to be a reflexive relation if every element of A is related to itself. Thus, R is reflexive iff (x, x)R for all xA. A relation R on a set A is not reflexive if there is an element xA such that (x, x)R. For example, consider A(1, 2, 3).
