Locally finite space

In the mathematical field of topology, a locally finite space is a topological space in which every point has a finite neighborhood, that is, a neighborhood consisting of finitely many elements.

A locally finite space is an Alexandrov space.

A T₁ space is locally finite if and only if it is discrete.
