A subset A of an ordered field F is said to be bounded below (or left bounded) iff there is p ∈ F such that. A is bounded above (or right bounded) iff there is q ∈ F such that. In this case, p and q are called, respectively, a lower (or left) bound and an ...

WebbThe infimum and supremum are concepts in mathematical analysis that generalize the notions of minimum and maximum of finite sets. They are extensively used in real analysis, including the axiomatic construction of the real numbers and the formal definition of the Riemann integral.
