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 n. The concept of locally Euclidean space is a central object in the definition of topological manifold.

Definition

A topological space X is locally Euclidean of dimension n, if for every point xX, there exists an open neighborhood U of x, and a homeomorphism ϕ:UVwhere Vn is open with the standard topology on n.
