“Antichain”的概念、定义、习题解题方法及翻译-数学辞典

单词	Antichain
释义	antichain A subset $A$ of a poset $(P,<_{P})$ is an antichain if no two elements are comparable. That is, if $a,b\\in A$ then $a\less_{P}b$ and $b\less_{P}a$ . A maximal antichain of $T$ is one which is maximal. In particular, if $(P,<_{P})$ is a tree then the maximal antichains are exactly those antichains which intersect every branch, and if the tree is splitting then every level is a maximal antichain.
