lower bound - a number less than or equal to every number in a given set. A lower bound (if it exists) for a nonempty subset B of a partially ordered set A (with ordering ) is an element d of A such that d b for every b B. Lower bounds are not necessarily unique; however, if c d for every other lower bound c of B, then d is a greatest lower bound of B . ;
