Solved examples of supremum and infimum
WebSupremum and infimum in [−∞,∞] Axiom + Observation: For all sets A ⊂ [−∞,∞] there is a smallest number larger than all numbers in A called supA – the supremum of A. Likewise there is a largest number smaller than all numbers in A called infA – the infimum of A. WebSo the supremum of your set is 1 / 2. For x ≤ 0, we have that x x + 1 < 1 / 3 is equivalent to x < − x / 3 + 1 / 3, and then to 4 x < 1, which is true for every nonpositive number. So the infimum of your set is − ∞. Another way to put it is to observe that the set under consideration is ] − ∞, 1 / 2 [. For the second set { − 1 ...

WebNov 27, 2024 · 0. So your set is. X = { n m: n, m ∈ N and 0 < m < n }. Claim: inf X = 0 and sup X = 1. You can easily see that both of them do not sit in X as m cannot be 0 and m cannot be equal to n. So in case we prove our claim, we can say that 0 and 1 are not minimum and maximum of X. This is because maxima and minima are required to be in your set in ...

Web58 2. 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′. If inf A and supA exist, then A is nonempty.
