WebA rank function of a poset P is a function r that maps elements of P to integers and satisfies: r ( x) = r ( y) + 1 if x covers y. The function r is normalized such that its minimum value on every connected component of the Hasse diagram of P is 0. This determines the function r uniquely (when it exists). Web1.

Standard examples of posets arising in mathematics include: • The real numbers, or in general any totally ordered set, ordered by the standard less-than-or-equal relation ≤, is a partial order. • On the real numbers , the usual less than relation < is a strict partial order. The same is also true of the usual greater than relation > on .
