Such spaces are commonly called indiscrete, anti-discrete, concreteor codiscrete. Intuitively, this has the consequence that all points of the space are "lumped together" and cannot be distinguishedby topological means. gymnastics romford

To see this, take an arbitrary countably … WebTo define the discrete topology, we declare all sieves to be covering sieves. If C has all fibered products, this is equivalent to declaring all families to be covering families. To define the indiscrete topology, also known as the coarse or chaotic topology, [1] we declare only the sieves of the form Hom (−, X) to be covering sieves. WebIf X{\displaystyle X}is finite then the cofinite topology is simply the discrete topology. If X{\displaystyle X}is not finite then this topology is not Hausdorff (T2), regularor normalbecause no two nonempty open sets are disjoint (that is, it is hyperconnected).
