Is an empty set reflexive
WebRemark 3.6.1. If A is an infinite set and R is an equivalence relation on A, then A/R may be finite, as in the example above, or it may be infinite. As the following exercise shows, the set of equivalences classes may be very large indeed. Exercise 3.6.2. Let R be the equivalence relation defined on the set of real num- Web1 feb. 2024 · 1) R is not reflexive 2) R is not symmetric 3) R is not transitive 4) All of these Solution: Since R is empty and S is non-empty, R is not reflexive. Since R is empty, R is both symmetric and transitive. Hence option 1 is the correct one. Example 3. How many reflexive relations are there on a set with 4 elements? Solution: Data:

WebThe full relation (or universal relation ) between sets X and Y is the set X × Y . 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 ) x∈E }. The identity relation is true for all pairs whose first and second element are identical. WebThe number of reflexive relations on an n-element set is 2n (n-1) How does this formula work? A relation R is reflexive if the matrix diagonal elements are 1. If we take a closer look the matrix, we can notice that the size of matrix is n 2. The n diagonal entries are fixed. For remaining n 2 – n entries, we have choice to either fill 0 or 1.

WebShow that the relation R=∅ on the empty set S=∅ is reflexive, symmetric, and transitive. Expert's answer A binary relation R R is called reflexive if (a,a)\in R (a,a) ∈ R for any a\in S. a∈ S. Since S=\emptyset S = ∅, it contains no elements. Therefore, the statement " a\in \emptyset=S a∈ ∅ = S " is false.
