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 ( … WebDetermine whether the relations represented by the directed graphs shown in graphs 23-28 are reflexive, irreflexive, symmetric, antisymmetric, asymmetric, and/or transitive.

By the way, “irreflexive and transitive” implies “antisymmetric”: if (, y) ∈ R and ( y,) ∈, then ( x) ∈ R by transitivity, contradicting irreflexivity.

WebAug 10, 2013 · A graph homomorphism is a map of the underlying vertex-set that preserves the edge-relation: if x x is adjacent to y y then f (x) f(x) is adjacent to f (y) f(y). If G G and H H are two irreflexive graphs, and G R G_R and H R H_R the corresponding reflexive graphs, then Hom (G, H) ⊆ Hom (G R, H R) Hom(G, H) \subseteq Hom(G_R, H_R), and in ...
