Contractible space - Wikipedia
A topological space X is locally contractible at a point x if for every neighborhood U of x there is a neighborhood V of x contained in U such that the inclusion of V is nulhomotopic in U. A space is locally contractible if it is locally contractible at every point. This definition is occasionally referred to as the … Zobacz więcej In mathematics, a topological space X is contractible if the identity map on X is null-homotopic, i.e. if it is homotopic to some constant map. Intuitively, a contractible space is one that can be continuously shrunk to a … Zobacz więcej A contractible space is precisely one with the homotopy type of a point. It follows that all the homotopy groups of a contractible space are Zobacz więcej • Fake 4-ball – Mathematic topological manifold Zobacz więcej • Any Euclidean space is contractible, as is any star domain on a Euclidean space. • The Whitehead manifold is contractible. • Spheres of any finite dimension are not contractible. Zobacz więcej WitrynaThen this space is weakly contractible. Since is moreover a CW-complex, it is also contractible. See Contractibility of unit sphere in Hilbert space for more.
