Connected space information

Connected and disconnected subspaces of R² In topology and related branches of mathematics, a connected space is a topological space that cannot be represented...

In topology, a topological space is called simply connected (or 1-connected, or 1-simply connected) if it is path-connected and every path between two...

uniformly connected space or Cantor connected space is a uniform space U such that every uniformly continuous function from U to a discrete uniform space is...

topological space X is locally connected if every point admits a neighbourhood basis consisting of open connected sets. As a stronger notion, the space X is...

locally simply connected space is a topological space that admits a basis of simply connected sets. Every locally simply connected space is also locally...

connected if, when it is considered as a topological space, it is a connected space. Thus, manifolds, Lie groups, and graphs are all called connected...

surjective in the case that X {\displaystyle X} is not connected. For every topological space X {\displaystyle X} , the identity map id : X → X {\displaystyle...

connectivity is based on the homotopy groups of the space. A space is n-connected (or n-simple connected) if its first n homotopy groups are trivial. Homotopical...

connected sets are. Each choice of definition for 'open set' is called a topology. A set with a topology is called a topological space. Metric spaces...

a totally disconnected space is a topological space that has only singletons as connected subsets. In every topological space, the singletons (and, when...

currently unknown whether the universe is simply connected like euclidean space or multiply connected like a torus. To date, no compelling evidence has...

Every hyperconnected space is both connected and locally connected (though not necessarily path-connected or locally path-connected). Note that in the definition...

unicoherent space is a topological space X {\displaystyle X} that is connected and in which the following property holds: For any closed, connected A , B ⊂...

path-connected neighbourhoods. A locally path-connected space is connected if and only if it is path-connected. Locally simply connected A space is locally...

any path-connected space Y, any two maps f,g: X → Y are homotopic. For any space Y, any map f: Y → X is null-homotopic. The cone on a space X is always...

a connected space, with one non-zero higher Betti number, namely, b n = 1 {\displaystyle b_{n}=1} . It does not follow that X is simply connected, only...

a connected space such that its removal causes the resulting space to be disconnected. If removal of a point doesn't result in disconnected spaces, this...

orbit space for this action is RPn. This action is actually a covering space action giving Sn as a double cover of RPn. Since Sn is simply connected for...
