Supremum of A Set of Real Numbers
In analysis, the supremum or least upper bound of a set S of real numbers is denoted by sup S and is defined to be the smallest real number that is greater than or equal to every number in S. An important property of the real numbers is completeness: every nonempty subset of the set of real numbers that is bounded above has a supremum that is also a real number.

“What is love itself,
Even though it be the lightest of light love,
But dreams that hurry from beyond the world
To make low laughter more than meat and drink,
Though it but set us sighing?”
