Upper and lower bounds

In mathematics, especially in order theory, an upper bound of a subset S of some partially ordered set is an element of K which is greater than or equal to every element of S. The term lower bound is defined dually as an element of K which is less than or equal to every element of S. A set with an upper bound is said to be bounded from above by that bound, a set with a lower bound is said to be bounded from below by that bound. The terms bounded above are also used in the mathematical literature for sets that have upper bounds.
