Greatest vs maximal element of set

WebDiscrete Mathematics: Poset (Least and Greatest Elements) Topics discussed: 1) Least element of a Poset. Show more Show more Web2.3.1 Upper bounds of a set; the least upper bound (supremum) Consider S a set of real numbers. S is called bounded above if there is a number M so that any x ∈ S is less than, or equal to, M: x ≤ M. The number M is called an upper bound for the set S. Note that if M is an upper bound for S then any bigger number is also an upper bound.

WebJan 2, 2024 · Maximal and greatest elements must both be elements of the set in question. As an example, take P ( N), the set of subsets of the natural numbers, ordered by inclusion. Now look at S ⊆ P ( N) defined the following way: A ∈ P ( N) is an element of S iff there is a natural number k such that all elements of A are powers of k.

Suppose that B is an upper bound for a set S and that B ∈ S. Then B = supS. Proof Let ǫ > 0 be given. Then B − ǫ cannot be an upper bound for S since B ∈ S and B > B −ǫ, showing that B is indeed the least upper bound.
