Which of the following are possets? a. (Z, =) b. (Z, neq) c. (Z, leq)
Which of the following are possets? a. $(Z, =)$ b. $(Z, \neq)$ c. $(Z, \leq)$ [5]
A partially ordered set (poset) is a set $S$ together with a binary relation $R$ that satisfies all three of the following properties: Property Meaning ------ Reflexivity $\forall a \in S,; a, R, a$ Antisymmetry $\forall a, b \in S,; a, R, b \text{ and } b, R, a \Rightarrow a = b$ Transit...
