Locally Euclidean space

A locally Euclidean space is a topological space that resembles a Euclidean space locally. Specifically, every point in a locally Euclidean space has an open neighborhood that is homeomorphic to an open subset in . The concept of locally Euclidean space is a central object in the definition of topological manifold.

Definition

A topological space is locally Euclidean of dimension , if for every point , there exists an open neighborhood of , and a homeomorphism

where is open with the standard topology on .
