Dini's theorem
WebDini’s Theorem 257 4 The Fan Theorem as an Equivalent of Dini’s Theorem A subset B of {0,1}∗ is detachable if u ∈ B is a decidable predicate of u ∈ {0,1}∗; that is, for each u either u ∈ B or else u 6∈B. To give a detachable subset B of {0,1}∗ is the same as to give its characteristic function χB: {0,1}∗. ‘‘. WebBenjaminR. Bray Probability: Dynkin’sπ-λTheorem November15,2016 Theorem 1, (Dynkinπ-λ). If C⊂P(Ω) is a π-system, then hCi λ= hCi σ. Proof. We already know hCi λ is a λ-system. Applying Lemma2, hCi λ is also a π-system. By Lemma1, then,hCi λisaσ-algebracontainingC,andsohCi σ⊂hCi λ.

WebHere is a partial converse to Theorem 10.4, called Dini's theorem. Let X be a compact metric space, and suppose that the sequence (f,)in C (X)increases pointwise to a continuous function feC (X); that is, f, (x)3fa+ (x) for each n and x, and (x) → f (x) for each X. Prove that the convergence is actually uniform. Web数学の分科、解析学におけるディニの定理（ディニのていり、英: Dini's theorem ）は、コンパクト集合上の連続関数の単調列がある連続関数に各点収束するならば、収束が一様であることを主張する 。. ルベーグの収束定理のリーマン積分版に相当するアルツェラの収束定理の証明に使われる。
