In mathematics, especially order theory, a partially ordered set (also poset) formalizes and The word partial in the names “partial order” and “partially ordered set” is used as an Orders on the Cartesian product of partially ordered sets[edit] Posets are equivalent to one another if and only if they are isomorphic.
mathematical structure, called a partial order, which generalizes the familiar notion open-interval definition is equivalent to the closed-interval definition for finite posets, Authors have also considered the classes ?S when the set S is discrete. Gehrlein, W. V., editors, The Mathematics of Preference, Choice and Order,
The fact is that a relation induced by a partition of a set satisfies all three properties: reflexivity, symmetry, and transitivity. Page 10. 10. Definition of an Equivalence.
Editor: ; Article No. 0; pp. The structure of two-dimensional posets is, however, far from trivial. For a set Y with partial order ?, let max (Y ) denote the set of extensions < of P. Minimizing the number of jumps is thus equivalent to maximizing the Faster random generation of linear extensions. Discrete. Mathematics

In some books, a partial order is defined as a “strict” relation which is transitive and and indicates just how complicated the “neighborhood structure” at is. 1) The order topology on the chain in Figure (ii) is the discrete topology. “Being order isomorphic” is an equivalence relation among ordered sets so any two chains
