## upper bound

If S is a subset of an ordered set A, an upper bound b for S in A is an element b of A such that xb for all x belonging to A.
An upper bound on a function ƒ with values in a partially ordered set A is an element of A which is larger than every element in the range of ƒ.

## upper bound

An upper bound of two elements x and y under some relation <= is an element z such that x <= z and y <= z.

("<=" is written in LaTeX as \sqsubseteq).
