Hausdorff space

Summary

A Hausdorff space is a topological space in which any two distinct points have disjoint open neighbourhoods. It is the most used separation axiom, and it makes limits of sequences unique.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
