(d) … WebLusin’s theorem does generalize to (−∞,∞). For each n ∈ Z, there is a closed set E n ⊂ [n,n+1] such that mE n > 1− δ 3·2 n and f En is continuous. Let E = ∪E n. Then E˜ is open with measure at most δ, and as before we may extend f E to a continuous function on all of R. 3 For n > 0 find using Lusin’s theorem φ

WebAs is shown in Figure 1, this implies thatA+B+A+B+⋯ is homeomorphic to the upper half space {(s1,...,sn) ∈ R n∣s 1≥ 0}. For a spaceM, let P(M) be the one-point compactification ofM. The above identification ofA+B+A+B+⋯ implies that P(A+B+A+B+⋯) ≅ Dn. In a similar way, the fact that B+A≅ Dnimplies that P(B+A+B+A+⋯) ≅ Dn. WebChapter 0 Exercise 16 We think Sn as the one point compactification of Rn.From this point of view, the inclusion Sn ⊂ S n+1is just the inclusion of Rn ∪{∞} inside R ∪{∞} given by the hyperplane x n+1 = 0 (and that identifies the points at infinity). Therefore S∞ = ∪ nS n is homeomorphic to R∞ ∪{∞}, where R∞ is the union ∪ nR n equipped with the weak topology.
