A manifold is a topological space locally homeomorphic to an open ball in some Euclidean space. The Whitney embedding theorem allows us to visualise manifolds as being 'embedded' in some Euclidean space.


A Topological space $X$ is said to be a Manifold if and only if

(i)$X$ is Hausdorff

(ii)$X$ is second-countable, i.e. it has a countable base.
