Webof ∆(P) are the chains (i.e., totally ordered subsets) of P. (The order complex of the empty poset is the empty simplicial complex {∅}.) For example, the Hasse diagram of a poset P and the geometric realization of its order complex are given in Figure 1.1.1. To every simplicial complex ∆, one can associate a poset P(∆) called the face WebAll Categories /. Discrete Mathematics /. Graphs and Graphs Properties /. 21.

WebProblem 11: (10 points) A subset of a poset is called an antichain if none of the elements of the subset are comparable to each other.

WebIt is common for people to refer briefly though inaccurately to an ordered set as an order, to a totally ordered set as a total order, and to a partially ordered set as a partial order. It is usually clear by context whether "order" refers literally to an order (an order relation) or by synecdoche to an ordered set. Examples:
