Is an empty set reflexive
WebIn constructive mathematics, "not empty" and "inhabited" are not equivalent: every inhabited set is not empty but the converse is not always guaranteed; that is, in constructive mathematics, a set that is not empty (where by definition, "is empty" means that the statement () is true) might not have an inhabitant (which is an such that ).

Check symmetric To check whether symmetric or not, If (A, B) ∈ R, then (B, A) ∈ R If (A, B) ∈ R, A ⊂ B.
WebBinary Relations Intuitively speaking: a binary relation over a set A is some relation R where, for every x, y ∈ A, the statement xRy is either true or false. Examples: < can be a binary relation over ℕ, ℤ, ℝ, etc. ↔ can be a binary relation over V for any undirected graph G = (V, E). ≡ₖ is a binary relation over ℤ for any integer k.
