Maximal element of a poset

Web6 sep. 2014 · Proof: Support that a and b are greatest elements of a poset A. since b is a greatest element, we have a ≤ b; since a is a greatest element, we have b ≤ a; thus a=b by the antisymmetry property. so, if a poset has a greatest element, it only has one such element. This is true for all posets, the dual poset (A, ≥) has at most one greatest ... http://hs.link.springer.com.dr2am.wust.edu.cn/article/10.1007/s11128-021-03156-3?__dp=https
