Hausdorff space

In topology and related branches of mathematics, a Hausdorff space, separated space or T_2 space is a topological space where for any two distinct points there exist neighbourhoods of each which are disjoint from each other. Of the many separation axioms that can be imposed on a topological space, the "Hausdorff condition" (T_2) is the most frequently used and discussed. It implies the uniqueness of limits of sequences, nets, and filters. (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Hausdorff_space)
