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.)

Web5 de set. de 2024 · That is we define closed and open sets in a metric space. Before doing so, let us define two special sets. Let (X, d) be a metric space, x ∈ X and δ > 0. Then define the open ball or simply ball of radius δ around x as B(x, δ): = {y ∈ X: d(x, y) < δ}. Similarly we define the closed ball as C(x, δ): = {y ∈ X: d(x, y) ≤ δ}.

WebA metric space is a set equipped with a distance function, which provides a measure of distance between any two points in the set. The distance function, known as a metric, must satisfy a collection of axioms. One represents a metric space S S with metric d d as the pair (S, d) (S,d).
