WebTransitivity requires that if ( a, b) and ( b, c) are present in the relation, then so is ( a, c). The fact that a = b in your particular example doesn't change that. You simply notice that ( 1, 1) is present and ( 1, 2) is present, so transitivity demands that ( 1, 2) be present. WebMar 12, 2024 · b $\in$ S, but (b,b) $\notin S \times S$, but in the definition we need that it holds for every element in S. Btw., if you doesn't make the prerequisite that it holds for every element in the set, you could directly conclude that every symmetric and transitive relation is also reflexive.

"WebJan 10, 2024 · None: in both cases, there's no such thing :) You mean "reflexive" and "irreflexive". A relation R ⊆ A × A is reflexive on A if a R a for every a ∈ A. Thus R is not reflexive on A iff for some a ∈ A, not a R a. A stronger condition than "not reflexive" is irreflexive. R is irreflexive on A iff for all a ∈ A, not a R a.
