A metrizable space is a topological space that can be endowed with a metric, meaning it can be described in terms of distances between points. This property allows metrizable spaces to inherit many useful properties from metric spaces, making them a central object of study in topology due to their rich structure and intuitive nature.

Metrizable Space

A topological space is a fundamental concept in mathematics that generalizes the notion of geometric spaces, allowing for the definition of continuity, convergence, and boundary without requiring a specific notion of distance. It is defined by a set of points and a topology, which is a collection of open sets that satisfy certain axioms regarding unions, intersections, and the inclusion of the entire set and the empty set.

A metric is a quantifiable measure used to track and assess the status or performance of a specific process, system, or activity. It provides a standard of measurement that enables comparison, evaluation, and improvement over time in various fields such as mathematics, business, and technology.

distances between points

A metric space is a set equipped with a metric, which is a function that defines a distance between any two elements in the set, satisfying properties like non-negativity, identity of indiscernibles, symmetry, and the triangle inequality. Metric spaces provide a framework for analyzing concepts of convergence, continuity, and compactness in a general setting, extending beyond the familiar Euclidean space.

central object of study

Topology is a branch of mathematics that studies the properties of space that are preserved under continuous transformations such as stretching and bending, but not tearing or gluing. It provides a foundational framework for understanding concepts of convergence, continuity, and compactness in various mathematical contexts.
