Open sphere in metric space

WebDe nition 11. A metric (or topological) space is compact if every open cover of the space has a nite subcover. Theorem 12. A metric space is compact if and only if it is sequentially compact. Proof. Suppose that X is compact. Let (F n) be a decreasing sequence of closed nonempty subsets of X, and let G n= Fc n. If S 1 n=1 G n = X, then fG n ...

WebA metric space M is compact if every open cover has a finite subcover (the usual topological definition). A metric space M is compact if every sequence has a convergent subsequence. (For general topological spaces this is called sequential compactness and is not equivalent to compactness.) Web3 de dez. de 2024 · The open ball is the building block of metric space topology. We shall define intuitive topological definitions through it (that will later be converted to the real topological definition), and convert (again, intuitively) calculus definitions of properties (like convergence and continuity) to their topological definition.
