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. … Visa mer 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 Visa mer 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, and their supremum is $${\displaystyle 0}$$ (which is not a negative real … Visa mer • Essential supremum and essential infimum – Infimum and supremum almost everywhere • Greatest element and least element – … Visa mer Infima • The infimum of the set of numbers $${\displaystyle \{2,3,4\}}$$ is $${\displaystyle 2.}$$ The … Visa mer • "Upper and lower bounds", Encyclopedia of Mathematics, EMS Press, 2001 [1994] • Breitenbach, Jerome R. & Weisstein, Eric W.
