Web10 Lecture 3: Compactness. Definitions and Basic Properties. Definition 1. An open cover of a metric space X is a collection (countable or uncountable) of open sets fUfig such that X µ [fiUfi.A metric space X is compact if every open cover of X has a finite subcover. Specifically, if fUfig is an open cover of X, then there is a finite set ffi1; :::; fiNg … WebTwo parts. Second one doesn't really warrant its own thread but I want to confirm it.

WebTheorem 14.3. If ε is an infinite subset of a compact set K then ε has a limit point in K. Proof. If no point of K were a limit point of ε then y ∈ K would have a neighborhood N r (y) which contains at most one point of ε (namely, y if y ∈ ε).It is clear that no finite subcollection {N rk (y)} can cover ε.The same is true of K since ε ⊂ K. But this contradicts the compactness … Webonly nitely many of the sets in C. An open cover is a cover by a collection of sets all of which are open. Proposition K. Suppose Eis a subset of R. The following are equivalent. 1. Eis closed and bounded. 2. Every sequence from Ehas a subsequence which converges in E. 3. Every open cover of Ehas a nite subcover. Names. The last two properties ... WebLet denote the set of all covers of the space X containing a finite subcover and let u ( X) be the set of all open finite covers of X. For we write where A (ω) = A ∩ εω is the induced cover of εω by elements a ∩ εω, a ∈ A. For any nonempty set Y ⊂ X and a cover write and N (∅, A) = 1. For we set also . bird hawk sounds
