What is the relation between metric space and topological space?

5 Answers. Just in terms of ideas: a metric space has a notion of distance, while a topological space only has a notion of closeness. If we have a notion of distance then we can say when things are close to each other. However, distance is not necessary to determine when things are close to each other.

Are metric spaces part of topology?

Theorem 9.6 (Metric space is a topological space) Let (X, d) be a metric space. The family C of subsets of (X, d) defined in Definition 9.10 above satisfies the following four properties, and hence (X, C) is a topological space. The open sets of (X, d) are the elements of C.

What is a metric topology?

A topology induced by the metric defined on a metric space . The open sets are all subsets that can be realized as the unions of open balls. where , and . The metric topology makes a T2-space.

What is space in metric space?

Metric space, in mathematics, especially topology, an abstract set with a distance function, called a metric, that specifies a nonnegative distance between any two of its points in such a way that the following properties hold: (1) the distance from the first point to the second equals zero if and only if the points …

Which is the topology of a metric space?

A metric space is a metrizable space X with a specific metric d that gives the topology of X. Note. In Section 34 a condition is given which insures that a topological space is metrizable in Urysohn’s Metrization Theorem. However, the study of metric spaces is more a topic of analysis than of topology.

When is a metric space said to be metrizable?

X is said to be metrizable if there exists a metric d on a set X that induces the topology of X. A metric space is a metrizable space X with a specific metric d that gives the topology of X. Note. In Section 34 a condition is given which insures that a topological space is metrizable in Urysohn’s Metrization Theorem.
