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. WebJun 19, 2012 · In particular, if a set has both a supremum and a maximum, then they are the same element. The set may also have neither a supremum nor a maximum (e.g., the rationals as a subset of the reals).

WebIf a set has a maximum, then the maximum will also be a supre-mum: Proposition 1. 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.
