This article defines a property of topological spaces: a property that can be evaluated to true/false for any topological space|View a complete list of properties of topological spaces

This is a variation of metrizability. View other variations of metrizability

Definition

Symbol-free definition

A topological space is said to be submetrizable if we can choose a coarser topology on the space and thus make it a metrizable space.

Relation with other properties

Metaproperties

Products

This property of topological spaces is closed under taking arbitrary products
View all properties of topological spaces closed under products

This follows from the fact that a direct product of metrizable spaces is metrizable.

Refining

This property of topological spaces is preserved under refining, viz, if a set with a given topology has the property, the same set with a finer topology also has the property

This follows immediately from the definition.
