The supremum and infimum Proof. Suppose that M, M′ are suprema of A. Then M ≤ M′ since M′ is an upper bound of A and M is a least upper bound; similarly, M′ ≤ M, so M = M′. If m, m′ are infima of A, then m ≥ m′ since m′ is a lower bound of A and m is a greatest lower bound; similarly, m′ ≥ m, so m = m′.
