Greatest upper bound

WebIn mathematics, the least-upper-bound property (sometimes called completeness or supremum property or l.u.b. property) [1] is a fundamental property of the real numbers. More generally, a partially ordered set X has the least-upper-bound property if every non-empty subset of X with an upper bound has a least upper bound (supremum) in X. WebUpper Bound. An upper bound of a set $\mathbf{S}$ is an element of k which is greater than or equal to every element of $\mathbf{S}$. For example: 7 is a upper bound of the …
