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}∗. ‘‘. WebDini's criterion states that if a periodic function f has the property that is locally integrable near 0, then the Fourier series of f converges to 0 at . Dini's criterion is in some sense as …

WebDini’s theorem: If K is a compact topological space, and (fn)n ∈ N is a monotonically decreasing sequence (meaning fn + 1(x) ≤ fn(x) for all n ∈ N and x ∈ K) of continuous real-valued functions on K which converges pointwise to a continuous function f, then the convergence is uniform. We look at what happens to the conclusion if we ... WebMar 13, 2024 · Denjoy-Saks-Young Theorem. Let be a finite real-valued function defined on an interval .
