Greatest and least element in poset

WebIn mathematics, especially in order theory, the greatest element of a subset S of a partially ordered set (poset) is an element of S which is greater than or equal to any other element of S.The term least element is defined dually. A bounded poset is a poset that has both a greatest element and a least element.. Formally, given a partially ordered set (P, ≤), … WebThe poset consisting of all the divisors of \(60,\) ordered by divisibility, is also a lattice. The divisors of the number \(60\) are represented by the set ... The greatest and least elements are denoted by \(1\) and \(0\) respectively. Let \(a\) be any element in \(L.\) Then the following identities hold:
