TopologyRelated: Connectedness captures whether a space falls apart under topological separation.
Open setRelated: Open subsets express the separations that connectedness forbids.
HomeomorphismRelated: Connectedness is preserved by homeomorphisms.
Identity theoremNarrower topic: Connectedness lets local equality extend across the entire domain.
General topologyRelated: Connectedness captures an unbroken structure using only open sets.
Hilbert–Smith conjectureRelated: Connectedness is an explicit hypothesis in the conjecture.
