Continuity theorem
Web131 Theorem 5.50: Let f be continuous on [a, b]. Then f possesses both an absolute maximum and an absolute minimum. 131 Exercise 5.7.3. Let M = sup {f (x): a ≤ x ≤ b}. Explain why you can choose a sequence of points {x n } from [a, b] so that f (x n ) > M − 1/ n. Now apply the Bolzano-Weierstrass theorem and use the continuity of f. Web2 Continuity of probabilities Consider a probability model in which Ω = . We would like to be able to assert that the probability of the event [1/n,1] converges to the probability of the event (0,1], as n → ∞. This is accomplished by the following theorem. Theorem 1: Let F be a σfield of subsets (called “Fmeasurable sets”) of a

WebSep 5, 2024 · Theorem 4.8. 1 If a function f: A → ( T, ρ ′), A ⊆ ( S, ρ), is relatively continuous on a compact set B ⊆ A, then f [ B] is a compact set in ( T, ρ ′). Briefly, (4.8.1) the continuous image of a compact set is compact. Proof This theorem can be used to prove the compactness of various sets. Example 4.8. 1

WebEgorov's theorem can be used along with compactly supported continuous functions to prove Lusin's theorem for integrable functions. Historical note [ edit ] The first proof of the theorem was given by Carlo Severini in 1910: [1] [2] he used the result as a tool in his research on series of orthogonal functions .
