Open covers real analysis
Webanalysis. Thus we begin with a rapid review of this theory. For more details see, e.g. [Hal]. We then discuss the real numbers from both the axiomatic and constructive point of view. Finally we discuss open sets and Borel sets. In some sense, real analysis is a pearl formed around the grain of sand provided by paradoxical sets.

The idea is that a compact space has no "punctures" or "missing endpoints", i.e., it includes all limiting values of points. For example, the open interval (0,1) would not be compact because it excludes …

If each set E i in a cover is open we say that {E i} iI∈ is an open cover of E. If the cover { } i iI∈ E contains finite number of sets then we call it as a finite cover. 2.

Fix p ∈ X. We have the open cover K ⊂ ∞ ⋃ n = 1B(p, n) = X. If K is compact, then there exists some set of indices n1 < n2 < … < nk such that K ⊂ k ⋃ j = 1B(p, nj) = B(p, nk). As K is contained in a ball, K is bounded.
