WebThe Supremum and Infimum of a Bounded Set Recall that a nonempty subset of is bounded above if there exists an such that for all , . And similarly, we say that is bounded below if there exists an such that for all , . We should note that these bounds are not unique. Recall the set of natural numbers .

In mathematics, the infimum (abbreviated inf; plural infima) of a subset $${\displaystyle S}$$ of a partially ordered set $${\displaystyle P}$$ is a greatest element in $${\displaystyle P}$$ that is less than or equal to each element of $${\displaystyle S,}$$ if such an element exists. … See more The infimum of a subset $${\displaystyle S}$$ of a partially ordered set $${\displaystyle P,}$$ assuming it exists, does not necessarily belong to $${\displaystyle S.}$$ If it does, it is a minimum or least element See more In analysis, infima and suprema of subsets $${\displaystyle S}$$ of the real numbers are particularly important. For instance, the negative real numbers do not have a greatest element, … See more • Essential supremum and essential infimum – Infimum and supremum almost everywhere • Greatest element and least element – Element ≥ (or ≤) each other element See more Infima • The infimum of the set of numbers $${\displaystyle \{2,3,4\}}$$ is $${\displaystyle 2.}$$ The number $${\displaystyle 1}$$ is a lower bound, but not the greatest lower bound, and hence not the infimum.
