This category contains results about Connected Spaces in the context of Topology.
Definitions specific to this category can be found in Definitions/Connected Spaces.
Let $T = \struct {S, \tau}$ be a non-empty topological space.
$T$ is connected if and only if there exists no continuous surjection from $T$ onto a discrete two-point space.
